No, I don’t think you are racist for that comment alone.

That being said TechTakes (awful.system) has lots of interesting content, but sometimes poor moderation principles.

I’ve seen them delete people’s comments on TechTakes for not fully agreeing with orthodoxy on a completely different instance. This was in context of a discussion side-thread about whether trans community in non-english-speaking countries would agree with every single initiative from the english-speaking trans community.
