“Honest” citizens know that is a really dumb line of thought

The hell they don’t!
All those dishonest people in government and all those dishonest people flooding across our borders are the reason we honest citizens need to own an AR15.

So you are saying you want to kill people in the government and immigrants with your AR15? Texas FBI offices should be notified of your intentions.

No. I never said anything remotely like that.

Only a person who desperately wants to win a losing argument would even consider that.

I guess you need to schooled on the reason for the 2nd amendment (and the AR falls directly under that amendment), to wit:

The 2nd Amendment is there for two reasons…
First, to give the citizens the means to rise up against a tyrannical government run amok.

From the Declaration of Independence…
“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,[NOW HERE IS THE CRUX OF THE ARGUMENT]--That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States.”
Can you grasp that?

The second reason is for the citizens to come to the defense of their nation were it invaded by foreigners.

AR15s are no comparison to 18th century muskets.

Yes. They are completely different.
So the f**k what?
I know , I know…you are so desperately trying to imply that the 2nd Amendment only applies to 18th century weapons technology…
Actually, the SCOTUS disagrees with you and agrees that it applies equally.

You mean the SCOTUS who can easily be bought by rich Republicans?

Delusional, much?

Notice that as soon as a leftist's political narrative falls apart and ideological talking points get blown out of the water they immediately shift into a slate of material that's been methodically debunked by experts for years?

It's as if all they KNOW is what their leftists teachers programmed them to KNOW during their ideological indoctrination -- er -- 'schooling' years?

Yes!

No, you are right the first time…indoctrination is the word.

Over six million unvetted illegal aliens allowed into our nation by leftists sine 2020; and now we learn that an unknown portion of those are probably members of terrorist cells? Honest citizens had BETTER have an AR15.
