Of course you're not. Most who try to pass themselves off as Republicans here aren't, as you have to be a US citizen to register as that, and the reason why most of them can't recall the name of their state they live in is because they don't live in one. Then there's the middle school set as well.
The anonymity this site affords allows those who can't get away with it as easily on sites like FB to congregate here. No need to explain to mummzy why Geoff is talking like he voted for Trump the year before he voted for Brexit.
But, then again, that's what scripts are for, innit?
