I have a very hard time folding to minraises

[n4rf]

I know that it's very situational, but whenever I am minraised from a villain, I find it much harder for me to fold unless I'm holding complete air. Let's say I hit mid-pair or top pair [censored] kicker on the flop and I C-bet it out, and villain minraises me. Am I always going to fold this?
I find it weak if I'm going to fold to a minraise every time if I'm unsure if I have the best hand.

Also, when it's a short stack doing it I find it even harder since most of the time I have the notion that shortstacks are complete donks (unless they have VERY VERY tight stats).

So what the [censored] is the deal with minraises?
