But of course its tarring them all with the same brush - don't you understand what that saying means? It's when you make an assumption that all people of X (race/job/background) are the same, or exhibit similar values, or at the very least are significantly more likely than average to have/do/be it.
You wouldn't apply that to any other feature (on the balance of averages hairdressers are much more likely to be stupid than other professions, scottish people significantly tighter than other nationalities, black people are generally much better at sports than any other race) so why would you do it for this one specific job?
To 'play the averages' you'd have to assume that a significantly higher proportion of police officers are terrible people it's too much of a risk to date - but there are nearly 100,000 male police officers in the UK - if you added together every single one of the cases that had hit the press recently you wouldn't even get 0.5% of that.
Who would benefit/lose out from me not dating someone wasn't the question. I'm not arrogant enough to assume that me swiping the wrong way on a police officer on tinder would ruin his life. The question was would you date someone, and I would. Because I'd see them as a ONE, i.e. an individual and wouldn't make any assumptions about their character from their job. Just as I wouldn't if they held any other job.
No, it's you who are not understanding. Stating a fact, such as 'Statistically, people who do a certain job are more likely than average to do X' is absolutely, categorically not the same as saying 'All people who do a certain job do X'. Neither I, nor (I assume) anybody else on the thread, thinks that all male police officers are terrible people.
And actually, yes I would do it about other jobs, and other things too. Not things like race, because that's different. It's an inherent characteristic, unlike career, which is something you have chosen, which says something about you. Your examples about Scottish people and black people are just stereotypes and are not backed up by my own experience.
