Why do people always antagonize the person asking questions?

They always respond with "you, you, you're doing this wrong, your beliefs are stupid". Cmon, am i crazy when i see this happening or am i overreacting? Because when i got to look for an answer to a question i have and there are many answers, some of them say "you'd have to be stupid to ask.
