I think you're correct. Approximate translations of the hashtags in the description:

#my little pony
#mlp
#my little pony
#board drawing
#pinkie pie

Is this supposed to be the pansexual flag?

I see the source is Chinese or something and I don't think they really do the pedo flag stuff over there. I assume this is supposed to just be pink plus the yellow and blue from her cutie mark. I think that's the primary reason certain members of the Mane 6 get associated with this queer shit is because they coincidentally share the colors of some gay retard pride flag. Some Derpi nigger probably just stuck that tag on there to further they/them's political agenda.
