But that isn't a reason to deny people help, deny people the chance to say "hey, look I'm feeling really alone right now". I wouldn't be as "tough" as I am now if it weren't for a few people who gave me a hand when I truly needed it. I wouldn't be where I am without reading a ton of blogposts by other marginalized people who feel the same way as I did.

There are, no doubt, people who like to wallow in their insecurities, but they aren't any worse than the people who say the marginalized should just suck it up and work harder, or that people who feel marginalized should shut up.

The phrase, "To the extent that you can..." was meant to convey the fact that the perfect ideal is not feasible. I also tried to make it clear that the attempt is worthwhile because even if your best is only an occasional success, you'll still wind up better off than you would otherwise.

On the question of toxic organizations, I'd like to point out that recognizing that the organization is toxic and choosing to be elsewhere was under your control. I commend you for making that choice. There will always be toxic people and toxic organizations. Some, like the police, we have little choice about dealing with. But there is no need to put up with ones that we can avoid. And by avoiding them, we make our lives better.
