I have that problem a lot when people are first told and explained I have BPD and what it is. It is a very aggravating thing. I described to one person how "every relationship I have been in has been abusive in some manner" and the response was "there goes your BPD again - I am sure it hasn't been EVERY relationship but maybe MOST, right?" I argued about a half hour and the conversation ended with the person saying "well, once you are able to have a more clear head and speak more rationally, we can continue this conversation."
That's just one of a ton of different occassions though.
