Why do celebrities like to boost their profile by speaking out for lgbt+black lives matter but ?

They do this because they feel that they must follow the crowd and, if they don't, they might be ostracized by those from whom they might, one day, need a helping hand.  Many of us are being intimidated, these days, to say things that we don't truly believe.  It seems to be a bad thing to have our own opinions (on many things) these days.  I won't 'go down that road', I am allowed to have my own thoughts and opinions and, if the day ever comes when we are not allowed to have those opinions I will want to leave this planet.

do not worry about it...GOD IS JUDGE not us.

We’re living in the “woke” era. It’s considered cool or trendy to talk about useless movements like Black Lives Matter and stick up for the gays. A lot of it is used for political gain and like you mentioned for PR purposes

Some are paid for such selective outrage

It's easy as people think them as victims forever

They don’t have to be right, true to who they are, or even accountable. They need popularity. Deep down, most of us want the feel good story, whether it’s right or wrong.

this racism thing has been a stigma on civillization for hundreds of years, all because someone doesn't have this same visual appearence, if you are against that , then sorry but you are clearly a racist, no butts
