Americans provide funding to the Irish Republicans because they see that the British always provided support to the unionists. They view the Republican cause as right and just.
You don't have any problems calling the Republicans killers, but just can't bring yourself to say the same about the unionists and the British military. Even though the Republicans are a defensive force and the unionists are an offensive force.
The conflict will only end when the north of Ireland is reunited with the Republic. One island, one nation, one people.
Yep, there you go, explaining how genocide is laudable, so long as you get to decide who gets killed.

Ein Reich, Ein Volk, Ein Führer
Let's get together and feel alright....(pass the ganja, mon!)
