My honest answer if you carry no psychological problem which prevent you to deal with that situation: Start looking for a new job and suck it up.

I doubt it will change and I've never seen in my whole life a company take some attitude against people like this in companies. They usually don't get promoted, but they hardly get fired, and if you complain about it, you are taken as the weak/prey, not somebody that wants the company culture to not be toxic. It's generally a losing game.

Some companies put upfront that they want a non-toxic environment and make sure to have a diverse team, that people follow guidelines etc. In an environment like this it's possible to remove this kind of toxicity. Otherwise it's hopeless. You'll look like the crazy person trying to fix a toxic company.
