So Catholics should apologise for the IRA's atrocities?
were IRA atrocities justified by the basic tenets of catholicism?
That's just the tip of the iceberg Ubik. If we apply that logic, every citizen of the UK is responsible for the wars in Afganistan & Iraq and each death that it caused. Every Jewish person is responsible for the actions of the Israeli government. The concept of Collective Guilt is odious.
you clearly didn't understand what I wrote. It's not simple membership in a group that does it. It's membership in a voluntary group whose central tenets relate to the actions or deeds being carried out. The distinction between a religion and the UK is that membership in the UK isn't totally voluntary, and neither afghanistan nor iraq were justified by ideas central to the UK. Thus, your analogy with the UK fails on both points.
as for the israeli government, some of the actions it takes are at least to some degree justified by the religious texts of christianity and judaism. For example, Israel's very existence on that piece of land is justified by both groups through their holy books. I don't know how central those specific passages are to either faith, but they are there in the OT and Bible, and are used by people (in particular, some jews and some american christians) to justify israeli ownership of that land. As for specific actions by the Israeli government, it depends on what we are talking about.
I obviously don't blame all muslims for the charlie hebdo killings, just like I don't blame muslims when Saudi Arabia executes someone for apostasy. But I do think that some muslims, certainly the ones that say apostasy should be punished by death (a shockingly high number do), are at least responsible for endorsing the ideology on which such executions are based.
