He/him, I share cyber wisdom, humor, and other info. If I’m upsetting Democracy’s adversaries. I’m on the right track.

My opinions don’t necessarily match my past, present, or future employers, but not for lack of effort on my part.

If you really want to get under the hood, enjoy this autobiographical song i wrote called “Without You I’d Not Be Me”.

Black lives matter. Trans lives matter. LGBT+ rights are human rights. Healthcare, security, a decent income, and housing with dignity are human rights. Abortion is healthcare. Science is our best hope as a species. Kindness and empathy are the noblest of human traits.

I block assholes and bigots.
