I don't know how you couldn't like same-sex shipping, In my eyes it's two personalities that are being shipped, My favorite ship Octavia x Vinyl is a prime example of this, Two polar opposite characters one Classy and refined where the other is very Upbeat and party-loving, If one was male and one was female in that example lots of people would ship it, It doesn't matter really what gender but personalities. Well that's my view on it anyway :3
