I don't go along with that sort of approach. That was just so extremely 'pc' that the message was toally lost.
If you have feelings about what someone says, why not say it straight out in an honest and clear way. I see no nobility in acting one way when feeling another.
There's no need to make it into a personal attack, just say how it made you feel. Honestly.
All that is needed is, 'I felt the response from Betty was too strongly worded'.
On the other hand, I think a lot of people get far, far too sensitive about what is said on the internet. A good many bb arguments I've seen were characterized by someone really, really working overtime to make something out of what was said that simply was not there. Twisting what someone said and making it into something it never was. Working hard to find something personally insulting, or to find something to attack someone about, is not a noble pursuit.
Just because someone has a different idea is no reason to get so offended by what they said.
Admitting one's position can help. 'I think everyone should feed XYZ feed because I like it', 'I tend to react negatively whenever anyone suggests calling a vet for an animal', 'I always advocate horses go barefoot - all horses', or 'I always feel when a woman complains about a partner, that she must be at fault herself, since I felt that way when my partner complained about me'.
The trouble is that most people are very, very reluctant to come straight out and do that. Because they know it sounds ridiculous.
So they'd rather try to convince people by a more roundabout method - even if it means browbeating or implying someone doesn't care about their animals - or some more PC approach that really is just veiled browbeating.
