Dave,
Keith, no matter how you phrase it, calling someone a liar and immoral is personal abuse as much as 'random abusive names' are.

No matter how you deny it, calling someone a liar in response to them lying is not abuse, and neither is disparaging the morality of someone telling nasty lies about someone while criticising them for a trivial slip three years earlier.
You make yourself look ridiculous by claiming it is "personal abuse as much as 'random abusive names' "
Of course it isn't!

We have not.
Case proved.
You lose.
