HOW CAN TOMMY ROBINSON AFFORD TO BUY UNDER ARMOUR GEAR?

Dunno.

How can he afford to buy Mossad gear? And Stone Island gear?

Perhaps it's the revenue from all the stuff he's published that reinforce the 9/11 myth that real-life actual muslims did 9/11 when we all know that the Anglo-American-Zionist Empah did 9/11. 

All I'll say this is: Jesus Christ didn't wear Under Armour.

And he didn't charge for the Sermon on the Mount either.
