Unless you have been in combat or an active shooter situation you do not know how you will react. Carrying a concealed or unconcealed weapon does not change the reality that without significant training all you may end up doing is firing blindly adding to the death toll. So please stop bragging about what you might do in a situation.
When only 3 of the mass shootings in the US within the last year were related to radical Islam, doesn’t mean you can just blame Muslims for all of the violence. This is especially true when one was committed by a radical Christian and another by a white supremacist. We have within this country a culture of violence; from the gun culture that lives in fear of the government and being unarmed to the glorification of violence in movies and on tv. Even this week we have heard from radical Christians who have come out in support of the shooting in Orlando, so this is not just a Muslim or immigrant problem despite how some people want to paint things.
Not only do we have a culture of violence but we also have a culture of hate, bigotry and complicity. From a presidential candidate who demonizes Mexicans and incites violence against protesters. To those who get their panties all twisted because African Americans want their lives to matter equally. Then there are those who think that because they and others like them hate President Obama, then he must be the most decisive president ever. Whiners who constantly complain about political correctness because they cannot use racial, bigoted or demeaning language without being called out for the bigots that they are. Then there are those who stand silently by pretending not to see or hear what goes on around them and their complicity fuels the bigotry and gives it more power. History teaches us that this combination can pretty quickly create a Situation where we fill slave ships, have Trails of Tears and fill gas chambers.
