...said no one ever.
Seriously, you've invented a very specific kind of fake person for your argument.
Which part? The ones who claim mental diseases aren't real, or the ones who call the city and report stores for not being wheelchair accessible?
I have personally witnessed both behaviors from the same person, and more than once (i.e., different people on different occasions). I don't think the hypocrisy of their world view even registers with them...maybe it's not terribly 'often', but it is ironic (and somewhat amusing) when it happens.
Quick exercise for you: Next time someone starts spouting off about how people shouldn't be diagnosed for (and apparently more importantly, get sick time off to deal with) depression or related illnesses, try asking them how they feel about wheelchair ramps, and whether *every* business should be required to install them. Or if not every business, then which ones have to and which don't? Then grab the popcorn and watch the high-wire act begin.
