> He liked the nationalistic display of a march in England?
Replace "nationalistic" with "fascist". That's the issue.

Umberto Eco gave a pretty well-reasoned definition of Facism, and I think it's pretty straightforward to apply this definition to the situation in London (and DHH's commentary thereon): https://en.wikipedia.org/wiki/Ur-Fascism
Just look up Tommy Robinson.
> He was a member of the British National Party (BNP), a British fascist political party. [1]
A march in honor of Tommy Robinson, who is a fascist. Not sure what else to tell you.

Post the rest of the sentence,
> He was a member of the British National Party (BNP), a British fascist political party, from 2004 to 2005.
