"The moderated forums feature a question-and-answer format focusing on issues that impact immigrants and refugees, people of color, individuals with disabilities and the LGBTQ community."

I fail to see the value in debating the above issues in a political forum.  With few exceptions you can't  even  openly debate these topics in college without creating endless protest (AKA riots), or being called a bigot, racist, islamaphobe, etc. I refer you to Evergreen State College as one example.   So to the candidates, go ahead and debate those issues.  Just remember, if you want to remain a valid candidate, you essentially have to agree with these groups, because their goal historically is not to promote speech, but to eliminate it and honest debate from the opposition.  Think safe spaces for the left.  On a side note, it would be refreshing to debate issues that affect tax payers.  See what I did there?  No need to drag race, religion or ethnicity or anything like that into the mix.
