Sincerely, you're asking for ideas, and there are other opportunities to vote besides the past presidential elections. If you don't find that suggestion helpful or think it was offered in bad faith, just ignore it. Getting heated or snippy isn't going to do much to encourage others to submit ideas.

Edit to add: And being able to not react reflexively to every perceived slight is itself a good suggestion as it's going to make you more effective in dealing with a lot of the polarization that's out there.
