Christians have a tendency to cherry pick historic events and twist the facts to fit their belief. For example; Hitler was not an atheist and christianity is not the only charitable institution. The christian community is the only group that claims any true innocence but we know different... Christianity has more blood on it's record and has committed more acts of genocide than any other religious group on earth. To disprove their claim as the most popular religion on earth, the average is less than 30% and falling. Even christians mark I don't know on religious poles at this point. So how is it that this disgusting brain poison still exists?
Most Christians are just ordinary humans that hide behind their religion to feel a sense of security and social acceptance like any other. It has been used for political ends and caused bloodshed among the people politicians manipulate just like any other. They are for the most part just morally and intellectually deficient as any other people on Earth. It can be argued however that Christianity promotes a false sense of morality and a false sense of hope and encourages herd-mentality in its orthodox western form. It is important then, to understand what Christianity is SUPPOSED to be and what 99% of its representation is.
Thankfully, Western Christianity is shrinking, and much of that is due to the shoddy tactics and 'lowest common denominator" Theologies. It cannot hold its own when it is not able to enforce itself socially or politically. It relies on Groupthink herd mentality to promote various doctrines, such as the "King James Only" movement which is a very common mentality or the "Bible is Infallible" approach where all scholarly work (That's not done on their side) is said to be ignored and not even considered. On this level, Christianity perhaps can be singled out as a religion that has not adapted well to Modern Philosophical thought and relies on whatever social pressure it can still exert to prevent serious questioning of its claims more so than others.
Christianity is, Biblically speaking, a form of what is commonly called "Messianic Judaism", but a FORM of. The current name-brand of "Messianic Judaism" is essentially Evangelicism with a bit of Judaism. The "Christians" in the Book of Acts were Torah-obedient, Nazarene-sect Jews who barely differed from other Nazarene-sects except that they believed Yashua was the expected Messiah to deliver them. And I believe he did in fact deliver them, and the destruction of the Kingdom of Israel happened just as it allegedly says he predicted. Jesus called himself a "prophet" and predicted the end of the Temple and the Hasmonean reign, and I believe it. What I don't believe however is what 99% of "Orthodox" Christianity and its unorthodox cousins believe.
What a "Christian" is supposed to be, as we see Biblically, is either a Jew or a Convert to Judaism who believes in the Nazarene Jewish perspective of the Messiah. That is, arguably, the most likely intended context of the Gospels and even is the basis of Paul's epistles, even if Paul was trying to change other's views. For example, Galatians is written in response to competition between the "Judaizers" over control of the movement, and it is here and Romans and other epistles where Paul's beliefs become entrenched. If you'll notice, most Christian doctrine does in fact go by Paul's teachings, and very rarely does Jesus's direct teachings get invoked. Jesus does in fact teach a saved-by-works doctrine, but this is not convenient whatsoever to the need to feel "secure in their salvation", so they water down everything Jesus says, even what Paul himself says, about what it means to be saved, removing the very basis for following the commandments.
Jesus has been turned into something completely outside of the likely intended context of the authors. His message and the Epistles and Gospels bearing them have been warped and interpolated and grossly misinterpreted and dishonestly mistranslated, we can only make our best guess what is authentic, what it means, what shouldn't be there, and what is missing. There are also many "Acts" and "gospels" that are rejected because they aren't in the Roman canon, but some present a very Jewish-Christian line of thought, such as the Pseudo-Clementines.
All other forms of Christianity ultimately allow their authorities to redefine whatever they want to consider "sin", as well as the rationale and reasoning for their particular documents because they have "De-Judaized" Christianity since the days of the Proto-Orthodox.
I personally do in fact believe that this form of Lawless Christianity where authority and definition of sin and how to interpret outside of the Nazarene Jewish perspective is fact as you say "Brain Poison", and it's because under this logic, there are no real rules especially when you don't even have to read what the text says at plain face value. Paul says that unrepentant fornicators don't go to the Kingdom of Heaven. Jesus says you cannot divorce. Yet they have all kinds of justifications with their concocted Theologies to trump and negate the plain reading of the text to suit their conveniences, that the very message of the story is lost amidst an attempt to "Cash-in" by making gentilized copies of the Jewish Messiah.
There is much difference between the Reality of the Jewish Christ in the Canonical texts themselves and 99% of the representation.
If Christianity is read within its Jewish framework, it's not Brain Poison whatsoever, it's Brain Medicine. But all the other forms of "Medicine", are according to my own belief, artificial imitations made of synthesized chemicals that don't actually work.
