It's not really so much as can't handle being called liars, or thickness of skin, it's more the downright disrespect AND slagging people's choice of dog off, whatever it is, apart from saluki crosses, that you keep churning out. And that's just two examples. I could give you several more, but it'd be pointless, as I don't think you're the type of person that's capable of taking it onboard.
There's a way of talking properly to people, whether you disagree with them or not, and it's with tact and decorum, both of which you seem to be severely lacking in.
