No, it is not my place to reprimand anyone.
I believe that my beliefs are true, but I am not claiming that they are true.
The only thing that will ever clear things up is if you accept what I just said about myself.
Please ask yourself why you cannot accept what I said about myself. Why is it so important to you that I say I am making a claim? I doubt you know why it is so important to you because the reason is probably subconscious.
It's in the way you say things. In my experience, you don't preface things with "I believe" or "my opinion on the matter is" and then go to state your opinion. You state things definitively.
Which is fine... but that IS THEN A CLAIM. And so, when it is a claim, you will be asked to back it up.
Hell... you may very well be asked to back up YOUR BELIEFS or YOUR OPINIONS!! That is entirely plausible! And people are NOT somehow being "a problem" or "remiss" in asking for your justifications for holding either beliefs or opinions.
I don't know why you have such a problem with being asked for justification! That's what this seems to be more about. You just don't like people questioning your sources and ideas. And so you think that by stating that you aren't making a claim, that this frees you from all responsibility to have to provide valid sourcing, support and reasons that you believe things or hold them as opinion. IT DOESN'T!!!
For example... I could state that it is my opinion that smooth peanut butter is better than chunky. Do you think it entirely implausible that someone might ask me why that is the case? I could then easily go on to state why that is the case by bringing up my liking the smooth texture, and that the chunky nuts are actually more likely to get stuck in various places in the digestive tract. These items all support my reasons for holding the opinion. And since it is a trivial opinion in the first place, this will likely suffice, or they may present their grounds for continuing to disagree with me. And , the reality is, if I simply state it as "Smooth peanut butter is better than chunky." without any qualifiers that indicate that I understand this to be my opinion and that others might differ, or I use language that strongly suggests that this is a true statement for everyone (Like "Smooth peanut butter is definitely better... this is logic 101 stuff"), well then... there you go. People would have every reason to gripe at me if they disagreed.
