I will address your last point first. Many JWs have piss poor education.
Some are homeschooled and others may not have finished high school. They are unaware of grammar and basic English and writing rules. This is why you see no paragraphs or some posting in all caps. I have seen some who don’t even capitalize words that should be. While this trend of poor grammatical skills can be seen everywhere and even in college grads, it is very pronounced among the JWs.
As far as JWs being rude, I think it has gotten worse in recent years. The women there are certainly awful.. The religion is getting more extreme and secretive and they see apostates everywhere, even under their beds. I also am of the opinion that the pandemic has made a lot of the older JWs cranky and disappointed because they expected to be in the ‘new world’ by now.
