How come people always downvote my art?

right so i was just looking at my art and i realized that people decide to be pricks on the website,  
some anthro ponies get more votes than my art, im just curious as to why anthro gets upvotes.

Don’t feel too bad. I only have like maybe 3 or 4 images that don’t have any downvotes.  
Some of my pics have as many as 38. I’m not really sure what was so wrong with most if them. Who cares 😁 I love’em all,even the crappy fetish ones.
