I took it as a parallel to that comic with the flag on the wall, the roommate says “so are you gay or something” but it’s a French flag or something.

Haha. I went to look for it and got this Evangelion edit:

Asuka hanging a flag on her wall. Her roommate says “So, are you like, gay or something?”
Asuka says “What?”
Her roommate says “What pride flag is that?”
The angle shifts to view Asuka with a disappointed expression, and we see that the flag she hung up was the German flag.
