I think it is pretty difficult to take anyone seriously who watches anime.
Why do you think this way about people who watch anime?
Because you have nerds who watch anime on TV, some people say 'anime is for retards only'
Just because they watch a show doesn't make them a type of person. You need to judge people based on more than that.
I don't care, I won't get associated with that people.
Someone watching an anime should not mean much to you at all as far as who they are as a person. People simply have different interests when it comes to television shows. Just because one person watches anime does not mean that they are uninteresting or weird.
