I wonder if there was a miscommunication? I understood you to mean that you wouldn't provide malware removal assistance to somebody who refused to run an AV, but I can see how it might have been understood as saying you would never help somebody anywhere on the forum if they didn't use one.
Just speaking personally I haven't used AV software of the likes of AVG, Avast, etc) for a good decade and also disable Windows Defender as well as the Windows Firewall where possible, but I use NoScript and uBlock and such in my browsers and keep track of my process/services to watch for anything amiss. as well as firing up MBAM occasionally.
I'd certainly never impugn AV software's value to the most users nor the quality of your assistance simply because I'm exempt from receiving it though.
