Yes, and I answered your question by saying I know a lot of tradies personally and many more 2nd hand through friends who employ them ie have been introduced at the pub at their xmas party or Friday drinks or whatever.
I didn't say I have friends that have the same views as me at all - not sure where you got that from.
Many of the tradies I know are left wing (and "PC") yet you admit you know only one, yet my circle is less broad? OK then.
I don't really care about the dick measuring contest you seem intent on. Broadening your circle was not in reference to the amount, it was the type. You freely admited you only know 1 left wing tradie, that ain't a very broad circle then cos there are s**t loads of them around.
The majority wouldn't be. Only my personal experience as a tradie myself and the hundreds i've worked with in construction, workshops and offshore. Anecdotal, but I'm sure you know thousands that are.
