These sort of statements - and others - is why some here have accused you of being racist.
The Blut und Boden hokey, bigoted crap?
Yup, that's a sure fire way to say 'take me seriously'.
Some people will naturally just not wish to engage with such a nasty little fuckwit anymore, and I can well understand and appreciate that.
But that ain't for me.
Racist twats like this either i) squeak ii) flounce or iii) learn.
I really doubt it's the latter here.
