Yes — I missed where you said “not just” instead of “not” in the first paragraph. Sorry about that.
I had seen further in what you wrote where it seemed you were trying to say it was for everyone, and it seemed incongruous.

I agree, the “you’re doing it wrong” crowd is irritating.  I think some of them mean it lightheartedly, though. 

 Could be language barrier, but "not just a social media" is not the same as saying "a social media not just for".
However the spirit of the note was very clear, and closer to your original interpretation.
Especially the part that says "your conservative bullshit thoughts are the last thing".

Shameful.
