You are getting caught up in cosmetics, not the actual functionality of the rifle.
I saw this great video once, and I'm linking to it here for you. It was made by a San Jose, CA cop in the 1980s when we were struggling with the assault rifle issue.
In it, he shows several rifles, and takes one with the wood stock, that you talk about, and totally converts it to an evil looking "assault rifle." Yet all of his changes are cosmetic. The action and barrel of the rifle never changes. He removes the wood stock, and replaces it with a black composite one with a pistol grip and folding stock. Then he screws on a bipod. And lastly swapped magazines. But the functional part of the rifle never changes.
So now, I am not bothered by a military looking weapon because I know it's really no different than a traditional sporting rifle.
What group are you in that's disliked by militias and right-wing extremist groups?
PS...thank you for your service in the military, and in being a teacher.
UPDATE: Last I saw, being gay was not something that was a visible trait. Unless you are at the range wearing your Gay Pride tee-shirt, they should not know, and thus you'd have nothing to fear from these alleged right-wring extremists.
