You may beg to differ all you like, however it does not change the fact that, being used as and being viewed as are two different things entirely. Now if there's instance of him going about and doing the very things that he despises about the men of blackmansfanclub then yes, there would be grounds for hypocrisy. You admit yourself that you make assumptions based on a few pics and a statement on his profile. Perhaps go and research what the blackmanfansclub does and then compare that to a merely posting a few cock picture's. I'm sure you'll see (whether you choose to admit or not) that they are nowhere near the one and the same.
I don't doubt that what the blackmansfanclub does could be considered degrading to some. Others apparently consider it at the very least OK because they are doing it. The are probably some who actually enjoy it.
The point is they are reducing the black men to sexual objects. What does Jstar's displaying himself as only a dick convey if not the same thing, a sexual object? I see no difference.
You can quibble over degrees of degradation or the style of presentation, but the bottom line is, whether it's a little or a lot, it's still sexual objectification and he shouldn't complain about it if he is going to do it himself.
No different than a woman putting on a push up bra and a tight low cut sweater showing cleavage to the max with her nipples poking out and then complaining because guys only stare at her tits.
