right, which more comes down to what you consider equivalent content.I don't understand how this is even a question. If one group is allowed to post content that the other group is penalised for, that's bias right there. It's obvious and measurable.
the obvious and measurablely wrong, like anti-global warming, flat-earthers, 9-11 truthers, antivaxx, alternative medicine, chemtrails, etc., would probably say they're being unfairly silenced. it's not an easy business, combating the crazies. do you stick to the extreme fringes and go for the easy-to-disprove ones, like mentioned, or do you go for political manipulation of facts too? how do you measure that exactly?
I'm not sure why you think it's obvious and easy to measure. what kind of content are you talking about?
