Agreed.
But discussing weapons is futile. Even if they were allowed to own guns (and it is against islam for non-muslims to be armed) that wouldn’t change anything for them. In these places the non-muslims are now so few that they are powerless against a muslim mob. A gun would only let them die with honour.
The ideal for me is to fight and *win*. Non-muslims in muslim areas are not in a position where victory is even a possibility. Nor is there any real chance for them to change that with armed might. But there are alternatives. -To leave, to go underground or to seek allies.
Christians would be better off buying cameras and internet access. Then every time the muslims burn a church or a Christian they could try to get it documented in a way that would encourage westerners to take note and support them like our ancestors did with the crusades and during the colonial period. If you see current reports on muslim atrocities they all lack the emotional impact that pictures and videos can have. Cold facts alone are all too easily ignored. People need to see Christian properties burn and Christians being slaughtered to wake up.
