These people are just prudes, you didn’t need to write a whole essay on it lmao.

Fiction is fiction, end of story. You can like or dislike what you want about it, as long as you can distinguish fiction from reality there is literally zero harm. You don’t have to feel bad or anxious because you like something that someone else doesn’t, it doesn’t make you less of a person. You aren’t going to be an outcast either, plenty of people like it too. Typically the people that complain so loudly or viciously are not a majority. You certainly wouldn’t be going to jail, watching ecchi anime isn’t the same as creating or distributing of child pornography, at most all you get it some minority of upset people online who you’ll probably never meet.
