The biggest mass attack in the US was with a bomb in the 1920s (
https://en.wikipedia.org/wiki/Bath_School_disaster). Guns have no bearing on these attacks. Its like people forget the boston marathon bombing or the knife attack in japan (or china?) a few years back. You can make a bomb with household items and directions you can find on the internet.
Guns are not the problem. Bring up factual information about this stuff. Most gun control advocates are not informed. Some of the main things these people do not know:
Most gun attacks happen in gun free zones
California has the strictest gun control in the nation
50% of research shows gun control works. 50% shows it doesnt. The research is inconclusive so for each study they show you it works you can show them one it doesnt. ie when they bring up australia or whatever.
There are mass shootings that have been stopped by ccw holders. They are not publicized but can be found with a 3 second google search. They are well documented. Here is one example that shows 10 instances -

Guns are carried every day buy tons of people. When you are at the grocery store, walmart, etc there are people walking around with guns - every time you go there and nothing bad ever happened. Most advocates do not realize this. They think making a school a gun zone means that people will be allowed to carry there but dont normally carry every where else.
you have a greater chance of dying falling down (among like 20 other things) then being involved in a shooting ever.
gun control is a bandaid solution to a cancer - the main problem is that our country is going downhill. jobs are being sent overseas. we are destroying other countries, etc. gun control doesnt solve any of this.
the best thing a gov can do to control its people is to take away its weapons.
AR15 and AK47 can and are used for hunting. In fact, they are what new rifles look like. Just as mobile technology has changed so has gun technology. AR is a technology just like any other. More deaths are caused by the iPhone (texting while driving) then mass shootings.
