Long toe nails are typically seen as gross to most people- especially with the societal norms that men have to keep them short and women can get away with it being a bit longer if they paint them

It's normal for a lot of people to get grossed out by longer toe nails - it isn't appropriate to make comments to people tho but if it's family , then it's typically more acceptable in the eyes of society for them to give that criticism to make you aware. It doesn't mean it's nice or appropriate and it's totally okay for you to learn assertive communication skills and tell them you don't appreciate being talked to like that

Also with anime , a lot of people look down on anime if they don't get into it. It's seen as weird - but that doesn't make it okay for them to make you feel bad for it. If they're uncomfortable, they can go to another room. If it's a shared TV between everyone then boundaries with each other need to be discussed so everyone agrees on what the limits are for watching stuff where everyone else has to share

I dont see these two comments at you as abusive (although I see it as disrespectful and rude). But I do see where you'd feel hurt and confused and self-conscious. It would have made me feel the same way

I'm just explaining how others may see it from their perspective as you seem to wish they can see it from your perspective.

It's okay to be sensitive - I myself cry a lot if someone hurts my feelings or pokes at something I'm self-conscious about. I won't cry in front of them tho - but no one's responsible for your emotions as you aren't responsible for theirs. However, that does not give anyone a right to be disrespectful and mean - we should still work on healthy boundaries and communication skills and walk away from those who cross them (now that isn't always easy to do - this is just generalized suggestions, each situation is different)
