I don't think it was as one-sided as you think it is; the host did a good job weaseling himself out of it. The layman, especially of the non-American variety, has no idea what the words automatic, assault and semi-automatic mean, Crowder didn't truly explain it. The host muddled the waters by bringing up the classification by the police, implying the police (authority) knows better. Crowder bragging about the gun on his hip wasn't a great move either, you can just feel people automatically putting him in the hysterical gun nut category.
Arguing that owning guns is a fundamental human right is a losing battle, especially outside the US. It's a right, not a fundamental one. Safety is a fundamental right, and that isn't directly connected to firearms. In the US every person and their dog owns a gun so it makes sense, in that context and that context alone, that the country is so flooded with semi-automatic guns that banning certain ones would achieve nothing. But the average viewer has no grasp of that, at best they came out of it vaguely understanding there is controversy on the subject.
