Giving an advice to someone else while it applies to yourself more than anything. Get off your high horse and stop being blind. So get informed before talking shit as you said.
It's been a common information that over exploitation of animals is a thing of horror. Many animals cannot even see the light of the sun, they are in small spaces, growing with malformations, some of them are aggressive even toward their own babies, we're removing teeth/ears/etc to some animals because they are going mad, and other fucking atrocities.
Just a quick search on youtube and you will get to see the truth.
I am a meat eater but since I know all this shit, I'm more picky on what I take and I eat a lot less meat. Same goes for the milk, I don't drink milk anymore, I'm more picky on the eggs I buy, etc. Being informed doesn't mean you have to stop anything, just consume better.
