You clearly have an image in your mind of a snarling, ignorant, racist thug, spouting bile and venom and ready for a fight. Not an appetising picture I admit and sadly I did see some of these characters at Wembley on Saturday! It is an obvious stereotype and a popular one.
A less obvious but equally obnoxious stereotype are the ' CRIMANABLES ' ( Chiswick.Richmond. Islington. Metropolitans. Anti Northerners. Anti Brexit. Liberal. Elite. Snowflakes ) Both stereotypes are at the edges of Brexit and Remain. One is in your face, arrogant, judgemental and unpleasant. The other is behind your back, arrogant, judgemental and unpleasant. It is a matter of opinion.
Criminables isn’t going to catch on. Way too clunky.
