I became a vegan when I was 15 (now 25) because I was essentially scared into it by PETA and I found them infallible, before I learned just what kind of organization they really are. In the last 4 years I've been a vegetarian, when I realized that I might as well live in the forest on berries to be truly vegan, and even then I'm sure I would disturb animal life. I just simply cannot fathom eating meat. It's no longer about animal liberation (which is insane, as rights come with responsibility that animals lack the intellectual prowess to handle and understand), and I know that I'm doing dick to help animals or to end animal suffering at this point.
I don't place animals as equal with humans, and I find PETA's equating the holocaust with factory farming to be grossly offensive and devalues human life more than anything else. I do believe that humans have a responsibility towards those "below" us, and to consciously avoid needlessly harming them or causing them undue suffering. I accept that, for many people, eating meat is as natural as taking a piss and I would never tell them not to or that their belief system is wrong. I would simply ask those in charge of providing the meat to not make the short life a complete living hell for the creature in question as it isn't necessary to create the food.
As to the "gastro intolerance" to eating meat, I have some anecdotes. My wife (who has been a vegetarian for 5 years) ate a piece of pizza that was pepperoni with the pepperoni removed, and the person who removed it didn't tell her. Within 10 minutes she had flu-like nausea and vomited about 3 times. She is a vegetarian simply because she never liked the taste of any meat her entire life, and after becoming an adult she had a more of a choice as to what was on the dinner table. It is not an ethical or moral issue.
My brother was a vegetarian for 4 years. His wife called him a "pussy" and "not a real man" and was tired of having to deal with 2 separate meals to accommodate his lifestyle. In response he ate a baconator from Wendy's, got incredibly ill (his face turned white and he looked like a zombie) and he couldn't keep any meat down for about the two weeks he transferred into an omnivore again.
I hate that simply saying "I'm a vegetarian" causes so much hate to be thrown at me, and at least one person deciding to be completely sarcastic and talk about loving animals (next to the mashed potatoes HAHAHA). I've never told an omnivore that I despised their lifestyle or to be so presumptuous as to attempt to program something so culturally significant as food for someone else. Please don't attack someone because you've had bad experiences with someone who identified similarly, as we are not a hive mind. Thank you for your time.
