Yeah, pretty much. Gerald Gardner invented a Horned God because superstitious people who believed witches were real and they had actual magic powers envisioned witches dancing with a goat-headed Devil, and Gardner wanted to be a "real witch", so he threw the Devil into his religion back in the 30s/40s/50s, but then turned around and said that it was really the gods Pan and Cernunnos and that those two gods are really one being, just as every non-Abrahamic god and every goddess all over the world is really one Horned God and one Goddess (see, that already sounds stupid. Don't be ripping off Hinduism, mister Gardner!).
This is laughable. Pan was a Greek deity that most people were afraid of (because he was the god of the woods, and people without modern day conveniences actually knew what the woods were really like). Cernunnos was a deity worshipped in Gaul (AKA France), and we have exactly ONE archaeological/historical record of his name, and several other horned/antlered supposed deities on artifacts discovered in what was once called Gaul.
Now what Gardner SHOULD have done was say that Cernunnos was the same as FAUNUS, which is actually plausible since Cernunnos is evidence of syncretism between Gaulish and Roman religion. It just made him sound stupid because as any kid who's read The Heroes of Olympus can tell you, Greek and Roman mythology were not exactly the same thing!
It's also stupid because Cernunnos was a GAULLISH deity, not a BRITISH one. This may come as a shock to many "pagans" who love to throw the word "Celtic" around, but the Celts didn't believe the same ******* things! Furthermore, the VAST majority of knowledge of Celtic mythology comes from Gaelic sources (specifically Irish) and Welsh because the Romans never did a good job of establishing their authority in Wales and because I don't think they even attempted to conquer Ireland. This is a problem for modern day Celtic "pagans" because almost all of that Celtic knowledge I just mentioned was written down by CHRISTIANS because they Celts had no system of writing of their own.
Beyond the obvious reason why this is a problem for Wiccans is also the fact the huge ******* time span between the Christianization of the British Isles and the Celtic era of Gaul/France. Celtic religion was long dead in France by the time Christian monks started writing down the pagans' stories, largely due to the pagan Romans' attempts to stamp it out (they had a strong revenge ***** for the Gauls, because of the Gaulish sacking of Rome).
Do you see how silly it is for a man claiming to be worshipping the ancient BRITISH Celtic gods to be naming his primary male deity after an obscure deity from hundreds of miles away who probably stopped being worshipped WAY before the British gods were ever written about in detail?
But wait, it gets even sillier! He claims the reason why his totally-not-Satan-witch-god is called Cernunnos is because this secret cult of witches worshipped THE EXACT SAME DEITIES ACROSS ALL OF EUROPE! But wait, it gets even stupider than that! THE WITCH CULT HAS EXISTED SINCE STONE AGE TIMES.
So yeah, basically, the Horned God is the Devil, only the Wiccans want to pretend that that isn't true. Other "pagan" witches are much more honest; Traditional Witches will flat out state that Satan is in fact the Horned God, but it's Satan who's just a demonization of the Horned God rather than the other way around.
Honestly, don't do magic; it's not real. Even Wiccans will defend themselves saying "it's just focused prayer". So in other words exactly what I and billions of other Christians do only without 30+ dollars of my money gone to spend on candles, herbs, smelly smoke stuff, fancy-looking knives (when you could just as easily pull a knife out of the kitchen), fancy-looking cups, and also all the time wasted spent creating a temple by casting a circle and calling of the elemental Watchtowers.
