I agree it was just immature taunting of the politically correct crowd. Helps nothing but is no big deal and will be quickly forgotten.
It is a big deal in my view because;
A) it's not a mere taunting, you have yet to demonstrate that
And
B) Even if it was a taunting saying rape is acceptable as some sort of sick joke provides cover for those for whom it is not a joke to say the same thing openly.
I remember as a young teen I used to make fun of Indians with another mate of mine. One day I married an Indian and when I did it my mate was shocked and like, "but dude, you used to make fun of Indians".
I realised at that point that it was only a joke for one of us and not the other for whom that taunting was motivated by real hatred.
I believe a similar scenario would apply to Fuentes and the rape crowd. Even if one of them is joking doesn't mean they all are. There are those who genuinely hate women - the whole incel movement being a classic example in my view and I only hope that if Fuentes is joking he has a serious wake up call and realises the kind of genuine hate he is helping to feed.
