these leftist clowns cant even admit the obvious, what we all know, what the medical community has proven true, that illegal immigrants from dirt ball, 3rd world sewers are bringing their diseases into civilized western countries. it's right there, it's the only common denominator.
And they wont even admit that. it's why it's pointless in even debating it with them..
Again, how can you prove this? Also, does the MMR vaccine not work against Mexican measles?
