Reminds me of the old uwu error message meme.
I think it's reasonable and fair, and something you are expected to tolerate in a free world. In fact, I think it's rather unusual to take this benign and inconsequential thing as personal as you do.
Thinking about it logically, putting some "serious" banner there would just make everything a bit more grey and boring and would make no functional difference. So why is it disliked so much?
I personally find anime kind of cringe but that's just a matter of taste.

This isn't about logic.
Clearly you proved that. What has sexual connotations is wildly subjective and plucking the opinion of one author/poet's critique from 15 years ago doesn't make it fact today.
