So someone who agreed with a person can never have an objective opinion on anything remotely related to them?
Therein lies the problem, because an 'objective opinion' is an oxymoron and does not exist. If we were talking about whether Humble Water Filter Merchant is an extremist, it would mean absolutely nothing if Humble Water Filter Merchant' biggest fan came on and said, "He's not an extremist because his views are
true! I should know, I have self-identified myself as a representative picture of American conservatism!"
If conservatives on the forums and in America were coming out in droves to support Milo, then I might reassess calling him an extremist. But the consensus among most moderate conservatives is that he's a cunt.
