gods, just drop it, watch it however you like, stop trying to convince other people your way is "right". If you can't read without vocalizing, then yeah, you're probably going to have problems with subtitles, if you can speed read, a sentence doesn't take long to read.
If you like dubs, that's great, if you think they're awful and like to hear the original actors, that's great.
seriously, it shouldn't affect your enjoyment of whatever when someone else enjoys the same thing differently.
