I don't want this to be seen as a personal criticism of the relevant commenter, since I'm often guilty of the same "careless" behaviour myself. But I think there's something not quite right about how What do you call a person whose ideology is derived from several opinions? was handled.
For those who don't have the rep to see the post (now deleted by the OP), the entire text of the question was...
Is there is a word for a person whose ideology is derived from several people's opinions/thinking/ideology?
...and the only comment posted before deletion was...
This is one of those relatively rare cases where le mot juste is fairly clear-cut (eclectic - deriving ideas, style, or taste from a broad and diverse range of sources), so I don't think it really matters whether the OP has provided an exact context in which to use the answer.
But I'm not putting up this post just to try and get the question reopened (though that would be good). My point here is that the only reason I can think of for the OP closing his (unanswered) question must be that he felt it/he was unwelcome.
In the spirit of "Be nice", may I respectfully suggest that we all1 make a bit more effort to avoid posting a "flippant, sarcastic" (potentially dismissive) comment as the first reaction to a question from a new user. If that new user might not see the funny side, it's probably inappropriate.
1 Okay, I know lots of established users here would rarely if ever do this kind of thing, so they don't need to change their ways. But I think that I do, and so do several others.
