Why would you spend time on a site where there are so many rude people? Yeah, there are a few kids that will respond to a question that they know nothing about just to see their name on the computer screen(presumably). But for the most part I feel like people are sincere in their answers, even if I do not agree with them.
too many trolls out there now a days, and plus most of us are badly slouched behind a computer screen, and have the power of the unknown. we can do what ever and say whatever without fear of consequence.
Dude you gotta understand: people are always jerks. Everyone is a jerk in someone's eyes. This fact has been and will always be true, so you're better off just accepting that rather than letting it bum you out :) hope this helped.
