Sweetheart, I'm pretty sure no one here actually hates male artists.
If you're talking about Robin Thicke, that date rape anthem deserves all the backlash it's gotten from this site and more. The fact it's overplayed only makes it worse.
Tell me then, what about male artists that is worthy of our attention? The presentation of masculinity, why sexually appealing is dreadfully boring in a pop music sense. Tacky, loverboy misogyny can only get a boy so far.
To be honest, the only male artist whose music I actually enjoy and find to be one of the greatest outliers of this obsession with the fantasy of masculinity is Drake - and even then it's not as if he's so wildly outside the norm. His brand is just a more 'sensitive' approach to hip hop that is so alien to the industry that everyone is so quick to call him "soft" or a "homo" or otherwise bash him just because he's not performing this draconian masculine ideal.
And as long as western male artists insist on performing this exhausted ideal in fear of losing their precious manhood, they will be nothing more than footnotes in the lexicon of pop music where only the daring and expressive (women) are worthy of our attention.
