Europeans do not lack the right to bear arms.
What they lack is the freedom to exercise that right.

What Europeans lack is a spine.

Considering no European has been asked if we want the Muslim horde anywhere on our Continent, when push comes to shove stuff like freedom to do whatever one wants will come bursting forth.
Excellent point.
That depends on the country. England is for all intents and purposes disarmed. Officially, the French are over 30% armed, but I would suspect the true figure is higher than that. Other European states have various figures from very high to nonexistent. You need to check each Nation State individually, but I believe England is the worst of the lot.
