I agree with you - Age does not make a difference.
It doesn't matter if you're being bulled when you're 13 or when you're 27: it still hurts, it's still upsetting and someone is still causing pain to you. I wouldn't want someone to bully my 5 year old sister or my mom who is in her 40s, it just shouldn't happen.
I think what stuck out to me is when you said "deal with it". I have heard that said to myself and others so many times through so many games that I don't think those people understand how hurtful it can be to feel like you are being bullied. Sometimes, ignoring that person doesn't work. Most of the time, if you deal with it, you end up being a lot more fucked than if you just let the person(s) attack you.
