Im not sure what his stance is on philosophy, if he likes it or not, I would assume that he doesn't really care that much about if that were the case. Yet I fail to see how that is dangerous?
Extreme forms of religions he is opposed to, don't think there is any doubt about that. But in many cases religions are harmful, and capable of planting bad ideas in people's heads. I don't think there is anyone that would deny that. And clearly he doesn't see any particular value in religions, especially when it comes to knowledge. Obviously this is up for debating, but religion does seem to have a fairly long and bad record history when it comes to being right about things, here im not talking about personally beliefs, but the knowledge which can be found and had been taught throughout history at the basis of religious beliefs.
This is also debatable.
If morality is in fact subjective then that is how it is, it is neither good or bad. Simply disagreeing with it, because one prefers that it is not, doesn't exactly change anything if that is not case, that would be to simply fool oneself. So don't really see how that is potentially dangerous either.
Well luckily we live in a world where people can do it, and religion being and still is the dominating approach, nothing prevent them for pursuing this, but one have to wonder, given how long and how little progress religion have made in regards to this for the last 2000+ years, whether anything will come from it. Even after that amount of time, there is no method or evidence put forward of how one should do it.
Almost all atheists (from what I know) are in support of humanism, so I doubt that dehumanizing and inhumane culture is in great support amongst atheists. And funny enough Richard Dawkins were actually awarded the humanist of the year in 1996 by the American Humanist Association, but lost it this year due to a comment he made
Doesn't religions teach that some people are better than others? That those who doesn't follow the religion is worth less than those that does? That those "special" ones gets rewarded while others get punished? Doesn't that sound slightly inhumane?
