There is no bullying culture on this site, Petra - in fact, the community will often pull up anyone who makes ad hominem posts against others.
However, if one asks for advice and then throws the time and good will others spent to dispense their hard-earned experience back in their faces, one should at the very least expect some negative feedback. Self-awareness and resilience are key to success in life.
On the off-chance you're not a troll, I'd advise looking at a flying career in the RAAF or Navy.
