Question for anti-vaxers?

Ok so I'm trying to see both sides of this debate but here is my question. If you think they are so bad do you think all moms should stop vaccinating? Like starting tomorrow no one else gets vaccines? Because what would stop all the diseases that are almost gone from coming back in full force? Say someone travels to a place whee those diseases are still very common or something like that? Would they not go through towns like wildfire? I have heard mom's say it's better to let them fight it on their own, it builds their immune system but what about babies or kids with weak immune systems? And some of the diseases can be fatal to older kids as well? This is a genuine question I have so thank you to all who answer with respect:)
