What do you think of Open Carry Texas and other gun groups trying to carry firearm in public places?

Honestly, I have never had a strong view on carrying firearms in public concealed or not. I own several firearms but don't feel the need to walk around armed even though I do have my conceal license and have been to several shooting course. Weapons are part of my job and I enjoy shooting them, I don't really consider them as a means of home security. But when I see groups like the Open Carry Texas trying to goto restaurants with not only pistols but assault rifles and shotguns a few things go through my mind. First, I see people that are looking for attention which they clearly get, as they act childish and smug when confronted. As soon as someone disagrees with them they throw out the 2nd amendment which was for self protection because our country was at war when it was written so common sense should be applied that carrying weapons is asking for trouble. When I say trouble I am talking about negligent discharges, confrontation, lack of training, and knowledge of weapons. What's the purpose other than causing a scene and getting attention. I love weapons and we should be able to own them but carrying them around in public. I mean there are plenty of countries where it is social acceptable to carry firearms in public, here are just a few: Nigeria, Algeria, Cote d’Ivoire, Zimbabwe, Sudan, Yemen, Sri Lanka, Gaza, Palestinian Territories, Pakistan, Democratic Republic of Congo, Iraq, Afghanistan, and Somalia just to name a few. What do all these places have in common they are really dangerous places, have little to no government, homicide rate is high, economy is terrible. Before we start preaching that we should be able to carry weapons in public areas think about how many safety accidents we have in the military where we train constantly proper weapons safety on a daily basis.
