You didn't sound like a hater, just like someone who thinks "don't complain, you're not the only one being hated. Accept it and go cry." Something like this.
While I do agree "idols" should know that unfortunately they will receive hate no matter what, I don't agree with this whole "decrease" about "oh it's just hate" when we clearly saw what it could cause to some idols.
Hating someone to the point where her/his mental stability is in danger.... Yes, it's pretty shit and it's ok to talk about it bc like me people care for their bias and tbh just caring for other human being.
Let's not accept hate as something common. It's just ugly.
The way I see it is promoting your faves so they know they are cherished despite all the hate that gets to them. Helping promoting them gets them their share of income which will help them in the long run. What I see being wrong with this is when Blinks go way beyond that to promote their faves by degrading what other groups do and that is my point. BP gets hate mostly because of its fandom rubbing them everywhere.
You are right by helping them get their achievements because you like them (I would do the same) but some are wrong when they go way beyond that and try making other fandoms feel bad. Just that.
