I'm loosely pagan on a spiritual level and I vibe a lot with druidism and many of the things that witches do, but as much as I enjoy the culture, I never fail to cringe over the collective hubris of self-proclaimed witches. It's always the edgiest 30-45 year old women who wear House of 1000 Corpses t-shirts and extreme amounts of eye shadow, who post "Proud Bitch" memes on social media and exude an undeserved air of confidence because they believe so deeply their spells are real.
While I admit that Wicca is quite beautiful and largely misunderstood, the things most witches/hexers are practicing only date back a few decades. They're not speaking the ancient magicks or communing with old gods. I can't speak much on the divine feminine because I'm not informed enough on that subject, but for the other half of their belief system they have taken the rather ambiguous depiction of Cernunnos and turned him into a sexy, big-dicked goat man, and have fabricated their own lore to explain the workings of something that is in reality unfathomably old and lost to man, with no surviving origin story and little to no oral tradition.
We can certainly make some educated guesses, but the bulk of that information died with the druids.
