Why I am not a vegan

[anagogy]

But there is a big difference: Many of the meat-eaters have repeatedly attacked US as people, with various insults regarding us personally, whereas we haven't done that to any of you

I accept that that is your interpretation of what was said, but I do not accept that is what actually happened (maybe in certain rare instances).  I'm positive that if you actually questioned the intent of virtually any previous poster whom you interpreted as personally attacking you, their intent had nothing to do with attacking you, personally, but rather simply pointing out an alternate perspective.

It's easy to confuse the two.  People often instinctively interpret the opposite viewpoint to theirs as an personal attack.  It's human nature.  I also think people oftentimes (perhaps even unconsciously) play the "personal attack victim" card to deflect relevant points, so they don't have to put forth a logical counter argument.
