Did the IRA or UDA ever allow pakistanis or blacks in?

Nigerians are now taking over Belfast and if whites deny this, they need to prove it

I doubt that the question ever arose. None wanted to join. 

As violent religious bigots, they would get on well with Pakistanis. 

The UDA? Very doubtful. 

The IRA, however, would accept anyone that supported their cause. 

The Loyalist community tend to have a very insular and racist outlook. Very much White, Protestant. Many Nationalists, having been discriminated against for much of their lives are more accepting of others. 

Potatoes.

They know a lot about spuds.

Ireland is a totally irrelevant country.
