Actually some animal fat is good for us. Cutting out all animal fat leads to a poor diet.
This is why science is so important. Science is about questioning everything. While we used to think animal fat was bad we've since learned otherwise.
Even if we are pretty sure about something it is dangerous to shut out debate. Except that which must not be named. Any questioning of this basic fact of reality is a sure sign you are not a man of science.
Only an idiot would be stupid enough to inquiry and debate. True science lovers accept the messages they heard on a video without question.
