"Everyone's so open and friendly" is a lie

Of the two - I feel like the "Toxic Casualism" is a better demon to have in the community. To be dead honest. If favors acceptance vs denial.

Quick correction, toxic casualism does not favor acceptance if it did they wouldn't mind you calling them out and would accept good advice or at least think about what is being said to them.
toxic elitism leans more towards acceptance than the prior as long as you give them the math they will do it.

What you're talking about is the fact toxic casuals don't call other people out because they're bad and don't want to be called out themselves, they're not accepting they just don't want to be put on the spot.
Toxic elitists do not care because they are doing what they're supposed to and if they're not they know they can do it and get better.
