Well, it seems to me that what's actually happening is that someone is being subtly manipulated to keep another person at arm's length and not answer questions, i. e., that it is an attempted form of ostracization.
I have answered many questions posed by people with whom I strongly disagree. If we could only answer questions from people with whom we agree, this site would be useless.
I agree completely, which is why I was so mystified by this individual's labeling of someone who answered my questions as a friend.

LMAO! There are some, but I don't have any.
Not me, but the person who did say that is indeed crazy.
