Honestly, this is pretty close to my stance on the whole issue.
I'm not a big fan of digging through people's history and using their old selves as a stick to beat their current selves with, unless they've shown persistent occurrences of whatever behaviour is being highlighted.
In this case, Kevin Hart has been called up for his homophobic tweets and jokes in the past, apologised then and hasn't faltered since which I think is the most ideal outcome.
Which begs the question, why is this being dragged out again, and why now?
That points me to the particular journalist who decided to spark this whole issue up, for a number of reasons, one of them being he accused Tyler the Creator of 'queerbaiting' when he came out as bisexual - which seems, nonsensical at best if you're a member of the LGBTQ community. The journalist seems to have a contentious history with black men, and the timing of this whole issue strikes me as opportunist. Also the relationship between the LGBTQ community and black men (gay or straight) is very peculiar - male white, LGBTQ members are of course discriminated against, but also have the capability to be racist - and likewise straight black men can be discriminated against, while also being homophobic - and both groups often are at odds with each other for those very reasons.
It's obviously a sensitive topic because you're dealing with two minority groups, but at some point these uncomfortable discussions should be had out in the open.
Those are the places where political correctness has gone too far, if it stifles constructive conversations & progression from being made.
Nobody gives a feck about song lyrics or PETAs attention whoring.
