Straight up question-- can animals be gay?
So, based on my findings? Uhhh... yes.

And some infographics, if such help:

So here's my question-- if homosexuality is so absolutely common across nature, then what are we doing putting it down so hard when it comes to us naked apes? Like, why is there any stigma whatsoever upon our sexual attraction choices, anyway?
Now, I hate to link to the Evil Empire, but this here dude seemed to offer some insights:

In any case, my current takeaway is this-- whatever one's attraction is upon others, such is completely normal, ordinary and common when it comes to Nature. We know that from the landslide of available evidence seen again & again, as above.
Which suggests to me that if someone's trying to tell you that there's anything wrong with liking whoever you're sexually attracted to, then chances are they're the weirdos from the healthy standpoint of Nature.
So "why are they doing that..?" one might ask. "Who trained them to be so strangely judgemental in the first place?" Those might be some followup questions...
