Making as assertion about someone telling a lie comes across as that, if you're given the benefit of a doubt and assumed to not be someone that calls people out as liars with little evidence unless you get carried away.
But perhaps calling people liars is a normal mode of communication for you, and you didn't lose your cool at al. That's definitely one way to interpret the comments so far, given how you equate "criticizing" to how you've presented your position so far.
I think you had good points initially. I also think that when presented with facts about this specific situation you've allowed you argument to devolve into a stubborn stand based on technicalities while belittling others.

Indeed.
