I did not read all this, just a few posts on the first page...
But I weigh 241. If I go under 300 grams of protein daily, I don't "feel" big. Not to mention, I can't grow. I am at 350-400 grams of protein per day. I simply can not grow and maintain a low body fat % on 1 gram of protein per day.
I do eat a good amount of red meat, so don't see the case against it. My chlosterol is fine. My lipid profile is fine. Everything is fine. I don't gain fat from red meat either.
