There is a colossal difference between planning to get a comic
based on the character, and then NOT purchasing it because the character is gay; and planning to get a comic IF the star is gay, and not purchasing it if the star isn't. Also, it's laughable to compare a desire to see representation in comics to open bigotry. I'm getting Daredevil, Black Panther and Black Knight; I clearly have no problem picking up str8 solo series. Someone who won't purchase a comic solely because of LGBT content isn't picking up any other LGBT comics (that's why their a bigot).
Firstly, let's remember who we are talking about. Hyperion is two years old in comics, and has very few stories really about him. It's a little early to say someone must be a well versed expect on the character to "justify" why (or why not) they should pick up his solo series.
Secondly, people pick up a comic for a great many reasons. For me visuals matter a lot (his costumes cool, as is Nightmask; I was instantly drawn to the character because of it). But budget is a very understandable factor. I have money to buy the comics I want, and little more to give
some comics a chance. I can't afford to try everything. And I want a gay solo star. Of course I would give Marvel's first ever gay solo star a chance (even though I don't know them that much).
Why would I spend money on a comic not giving me what I want?
