Miss Kobayashi's Dragon Maid - 翔太君はよく夢を見るなぁ

It may be old news but Coolkyou must be happy knowing that his creation is animated. If I were an artist I'd be happy as hell knowing that.

That one actually had a believable, if rather ignorant and uneducated, reason behind it (The original line having potential to be seen as insulting towards lesbians if taken literally).
The one where Lucoa mentions "the patriarchy", however, has no excuse. That's just Jamie inserting her politics where it's not welcome.
