Nicely put forward argument TB, but I do have some questions/observations:

The same for when the car behind you has its front foglamps on - I personally don't see them as a problem at all.
Now rear foglamps are a different story and incredibly annoying since their beam does affect your vision.
Even more annoying are misalligned front headlamps which dazzle you.
Fair enough (usually) if the fog lights are well aligned, but they often are not, and even when they are, they're more prone to reflecting up off a wet road surface than normal lights. You mention mis-aligned headlights, but that's a much less likely phenomenon than mis-aligned foglights. Headlight aim is checked on the MOT, foglight aim is not.
Lights on during the day apparently reduce your chances of an accident quite significantly - hence Volvo lights that are always on.
BTW Safety statisticians apparently recommend full lights (dipped) as opposed to just parking lights during the day.
Very true. I use lights (not fogs) whenever it's dull or visibility is reduced in any way during the day.
I have two confessions to make about front foglamps I use them on windy roads at night because it improves the visability of the kerb around tight corners in the absense of adaptive lighting that some marques have.
I'm not buying this at all. It's an argument I've seen many times before, and it just doesn't hold any water at all. I would concede that it gives you the impression
that it's helping, and makes you feel safer, but it can't have any valid effect whatsoever. The distance ahead of you that correctly aligned foglights illuminate is so small that the only way they can help your judgement of the road ahead is if you're travelling at about 10mph. They illuminate the verges about 10 feet ahead, max, and if your reflexes are good enough to use that information when driving at normal speeds, you should be in F1
Of course, your foglights could be shining further ahead than that... but if they are then they're badly aligned, and you're one of the people dazzling others
I also sometimes use them with parking lights at dusk for the short pre dusk period before I switch to full lights attempting to be more visible at one of the most dangerous times of the day.
Why not just use your dipped headlights? That's what they're for. If you search deep inside yourself, is there any actual valid reason other thawn 'it looks cooler'?
I'm guessing this makes me a bad person
Nah. Just misguided
It comes down to one simple point, foglights should not be used unless visibility is down to less than 100 metres even with headlights on, and there is no benefit to using them anyway unless that is the case.
