That's what the comment section is for on the original post.

By doing this you are intentionally trying to use another redditers post to invoke a reaction within an alternative community that is more likely to agree with you. 

AITA is a forum for a plethora of reactions from people on a given subject. You should comment there. 

If you are finding that the opion you have is proving to be unpopular, then reposting it here for a positive reaction makes the whole point of this subreddit illogical. 

I think this is the equivalent of doing a country acoustic cover version of a hip hop tune. Unnecessary.
