If B then A is the same as if X then Y is the same as if A then B. They are saying it's the same as the OP. Changing the letters around doesn't change the meaning since the letters are just placeholders.
Now if you said If A then B AND If B then A as one it wouldn't be the same because A and B would have to keep the same meaning.
I also love audience participation and I find people sitting are 10 times less likely to participate. I haven't found it common but being able to buy a seat but still stand and mosh etc is ideal.
The only reason I left is removal of third party apps. The more Lemmy users shit on the rest of it the more likely I am to return occasionally on desktop cause it makes me think people here dont want the same things I want, or actually have problems with the things I want.
