Went back and watched the part of the first video showing footage from the march in London, and it finishes with a snippet of a group of blokes singing the 'no surrender to the IRA' chant which:

'[...]derives from the 1689 Siege of Derry during the Williamite War in Ireland.[1] The song is associated with unionism and particularly Ulster loyalism. It expresses opposition to the Provisional Irish Republican Army (IRA), which carried out hundreds of bombings and killings targeting British security forces and civilians during the Troubles.[2] The origins of the song are unknown but it was chanted in British pubs in the 1970s and 1980s and has been associated with the National Front and the British National Party.[3][4][5]

The song came to be sung by Rangers F.C. supporters, many of whom have strong unionist beliefs, in contrast with the pro-Irish republican sentiments of many supporters of Celtic F.C., their Old Firm rivals. The song may have been popularised among English football fans after the Heysel Stadium disaster in Brussels in 1985, which resulted in a five-year ban on English clubs competing in UEFA competitions. Some English fans chose to follow Scottish clubs instead and Rangers, one of the more successful, attracted a sizeable English following.[2]' - https://en.wikipedia.org/wiki/No_Surrender_(to_the_IRA)

Pricelessly Brand then asks: 'are people allowed to be patriotic, are people allowed to be nationalistic' with the clear implication that he thinks they should be (though who he thinks does the 'allowing' in this case is unclear). But what kind of patriotism or nationalism makes this kind of aggressive insistence on defeating a resistance group in a foreign, occupied country? Surely this is the kind of racist imperialism that wants to enjoy the fruits of empire & colonialism and make sure all the costs remain externalised.
