Any woo-based profession where you make money selling lies and snake oil to gullible or ignorant people. This includes almost all alternative medicine practitioners, religious leaders, anyone in the psychic community and right wing "news" outlets.

If their bio said "current President of the United States," that would probably be a dealbreaker for most of us

Hunting guide, slaughterhouse worker

Being a preacher in a fundamentalist church.

Politicians
Defense Lawyers
Psychics
Cops
Judges
Strippers+
Correctional Officers
Clergy

working at the KKK would be worrisome.

I hated the military...
Also politician , lawyers or judge. Most of those people are pretty obnoxious

Work in a slaughterhouse - in any capacity.

One of those deodorant sniffers... or porn fluffer...

Prostitute lol

Aside from the silly answers (porn star, hooker) if they have a job, that's a good start. I wouldn't try to be petty about what someone does to pay their bills.

That's a tough one I can't say that any profession would put me off. Sometimes you just have that job at that time to pay the bills. My job is not satisfying or even attractive too most. Just the one I have.

Republican politician or staffer for same
Evangelical clergy of any denomination
Unemployed
Under the table income stream

Connecting with someone else, my only turn-off would be if they were a clergy member which doesn't seem possible on this site.

Though it wasn't asked, the only career I am turned-off of from pursuing is being an Economist or Accountant or anything related to the economy. What a waste of mathematical talents...

I'd message an Economist/Accountant on here but thinking on it more I might have some reservations, probably couldn't talk about work...

maybe mortician or prison warden

There's many like live fox skinning or seal battering

Dental hygienist

i am OK with the military, I would have issues with clergy. I would have issues with unemployment, depending on the reason. I've met several men on free dating sites that were serial unemployed with emotional or alcohol problems. I don't think a truck driver would work out, I don't do long distance.

I'd think twice about sales, and MLM would be a turn-off, also anyone who would be either a "self-help" specialist or motivational speaker.

I'm probably not a great partner for anyone who is looking for a partner that can help win over new business clients either (my ex even said this when she asked for our divorce), that may rule me out for anyone at a start-up or of an entrepreneurial stripe.

Sunday school teacher.Lol

Divorce Attorney!

Not sure I would want to date an attorney, they spend all day trying to convince on arguments of cases set by courts that are blindly based on religious principles.

Not many would put me off but I would say being an escort might make me back off.

Prostitute, police, con artist.

Politicians (nothing bores me more than someone who thinks they'll change my mind by constantly arguing their point)...people who work for companies I find do reprehensible things (cigarette distributors, corporate lawyers, etc.)... anyone in the field psychotherapy (specifically session therapists, who try to second-guess and find 'meaning' behind everything you do, no matter how mundane)... That's a good start to my list...
