It would be far easier in the UK because everyone is legaly disarmed, you have survelience everywehere and you can easily pinpoint those you wish to persecute. In the US it would still be possible but you would run into resistance that caused more casualties in the forces employed to round up those to be persecuted. This would stall the genocide and cause a more long term resistance. In the UK however genocide would easily move forward as the death squads moved from house to house clearing unopposed, and able to easily dominate those that did oppose with no casualties.
The cost of genocide in America to a government would be so expensive and costly to the lives of those employed to do it as to be prohibitive. You could twist the encounters in the media to still have majority support by painting the resistance as psycos or criminals, but it would still be costly. In the UK however it would be easy to slaughter a selected people like livestock with nothing but outcry, no actual dangerous or costly resistance.
Guns support a mindset, even if they are not the deciding factor.
