Heh; in my response to the email in which I was scolded for having opinions, I said that not allowing discussion or dissenting opinions leads to an echo chamber, which is a bad thing. (Even though both this person and I agree, on the larger scale, that modern industrial farming practices are horrible and need to change.)

I mostly roll my eyes at the ultra-conservative stuff that rolls across my facebook feed (though there isn't much of that, thankfully). The anti-gay stuff is more annoying, but mostly I ignore it, because I don't have time to argue on facebook with people I went to high school with.

If you already have a very sheltered view of the world, and your only source of information on topic X is from one side (and good lord there's a lot of misinformation and pseudoscience and anti-science garbage in the anti-industrial-farming, slow foods, etc movement), living in your sheltered echo bubble is akin to being a Fox News viewer.
