Milo was one of the most hated people by the alt-right, his husband is black, how much more do you need for him to most probably no being alt-right?.
I refuse to believe that anyone who sincerely and honestly spent any time looking into the actual opinions of Milo, Ben Shapiro, Molyneux etc and not just cherry-picked soundbites would make such claims about them. Milo is extreme in his provocations but he is hardly anything close to alt-right.
I certainly don't agree with everything these guys have to say but I would urge you to actually listen to what they are trying to say before you judge them.
To the downvoters. At least provide me with a reason for the downvote. What did I say that's so wrong?
