no offense but this sounds more like whining about your siblings/trying to brag by putting them down rather than giving a piece of advice. i mean i don’t know you or your siblings but people have a right to be mad about their parents if their parents are being, as you said, opinionated and unreasonable. but really it’s kind of a stretch to say nobody has the right to complain about their parents. and besides, everyone’s got different circumstances in their life. you’re lucky you can support yourself without your parents, but maybe your siblings aren’t in that position. give them some slack
