"Dairy farms are filthy, disgusting things. Go visit one some time. You'll never drink milk again."
How many farms have you actually visited? And by "visit", do you mean actually gone to, or just driven by?
My family's dairy farm is gorgeous. Every single dairy farmer I know (and I'm quite certain I know a lot more than you) takes fantastic care of their animals and takes great pride in their farms. Of course, there are some who don't, but those are few and far between. Don't take the exception to the rule and try to use it to make a false generalization of dairy farms.
