ENOUGH IS ENOUGH:
I understand your point.
Unfortunately, what you have seen with regard to insults about ‘window washers’, ‘housecleaning’, etc. is a backlash against Witnesses who had these jobs in the congregation but who stupidly knocked other Witnesses that had college or white collar jobs.. They acted as though theirs was the only ‘approved’ 🙄work.. And in the eyes of jealous, judgmental Witnesses it was.
In the Witness religion there is/was a terrible bias with regard to college educated and/or those who had decent white collar jobs. (God forbid if you’re a woman.) SO, this is why the insults against the types of work you mention are plentiful and in some cases well-deserved.. In my opinion, the JWs have brought it on themselves with their wrong attitudes, envy and ignorant bias.
