Look man there are several different ways people argue and calling someone a liar or saying a policy is cruel despite the official line is entirely reasonable. If you’re taking that so personally that you have to personally respond to everyone about that then I have to wonder if you’re just trying to defend the policy in a motte and then retreat to the bailey of “I don’t support the policy I just don’t like how you’re arguing.” Calling someone cruel or a liar is not a slur, they’re calling out what they view as shameful acts. I think it’s within the bounds of civility to call someone cruel or a liar. I really think you’re just trolling with repeated requests for civility here.
Calling someone a liar is not an argument.
