I am sorry you feel you had to leave over the comments of a poster. In any community of people you will always find a variety of people with a variety of ideas and manners. Getting upset because someone was rude is understandable, but demanding apologies and insisting that others be banned for them is just setting yourself up for disappointment.
I used to get upset when people made personal attacks, or misconstrued my words, or disagreed with me, and of course it hurt my feelings. But I found responding defensively just started a negative back and forth that just never ended. I finally realized that It's entirely possible to just ignore comments and not respond in any way. Really, not only can you, but it's best. Often bullies are looking for that response, it's the payoff for them, so refusing to engage is the worst thing you can do to the. So what if they insulted you? Take the long view and be the better person and refuse to respond in kind, or even respond at all.
If anything I feel sorry for anyone who needs to act in that way, as it tells me they are not happy in their life. It's just words in the ether, not meaningful in my life to any way, really. In our previous life as Jehovah's Witnesses there was unity and firm rules, but that unity was at the cost of intellectual freedom and choice. I treasure the right to disagree, to say something is bunk when I think it is, to defend my view point. I would not want to be on a forum that was so heavily moderated as to eliminate all controversy. I also see that many here have made personal attacks on Viv that are worse that her original rudeness, imho. I personally feel that she bothers people so much because she is most often right, but it's easier to get upset with her rudeness that counter her logic.
But of course you can choose to go, if negative comments bother you that much it's probably best. Being an Ex JW is hard enough, you don't need to add any more stress. But I think we are a better community if we have a variety of viewpoints, so I would wish for you to stay, ignore the negativity and continue to contribute your unique opinions. In any case I wish you well and hope the decision brings you peace.
