Some of the “legal” factory fog lights are blinding as well, new Ford F products come to mind (especially lifted rigs with LEDs). Unfortunately using these factory lights in times when they are not warranted is becoming the new normal - sure YOU can see better, but at the expense of everybody else that you pass or get behind. I used to “return the favor” but that only increased my angst thinking about it. Trying to let it roll off of my back lately and have a nicer drive, I can be the better person. What is REALLY hard is not enabling my VisionX reverse lights for tailgaters. :) For what though? A possible conflict?
I drove 4 hours last night, out and back, to recover an OB member - he was stuck but good, hahaha. It really sucked when oncoming traffic blessed me with their fog lights on the return. Really tired, early AM hours, dry good conditions. Yay, you can see better while broadcasting your disregard for others.
Don‘t feel strongly about this at all. Hahahaha
There are many people who have the sentiment of "fog lights should only be used during certain circumstances!!!!" But, I use mine all the time, and it infuriates those people (online forums). Fog lights, when done properly, will always be below the driving beams. My Q60 utilizes LED fogs, and as I back out of my driveway, I can see they are a sharp, horizontal slit of light clearly delineated below my main driving beams. They never would offend on-coming traffic. I can't speak for Fords, however.
Since I see you are in WA state also, you likely drive on hilly, undulating roads. Whenever a vehicle crests these roads, those oncoming under the elevation you are at may feel your lights are "too bright". Often, they are not too bright or mis-aimed (or improperly turned on) it's just the nature of hilly roads.
On a tangent, we are due for a significant tax increase for roads here that will never address the lack of proper street lighting, which could improve how we perceive oncoming vehicles when street lighting would provide contrast.
I too, have incredibly strong rearward facing LEDs on my truck (for boat launching and off-roading) and I could use them on idiots behind me, but I don't. Fortunately my truck camper significantly dims any too-bright lights behind me!
The real issue is with people who go through life with "indifferent aggression" as I like to call it. It's not just those running HID bulbs in their Ram 1500's, LED light bars on the road, etc, it is also all of those idiots who drive with their high beams on, and no amount of "flashing" them seems to affect them, they leave their high beams on. I totally trashed some guy on another forum for gloating that his LED headlight bulbs caused others to flash him constantly but he "didn't care LOL".
No matter your vehicle, if people are always flashing you, you should consider why. Maybe it's the OEM fogs bothering others, OEM LED headlights that need to be re-aimed, or aftermarket LED/HID bulbs that need to be removed.
