What's Mistletoe Got To Do With Xmas?

I haven't seen a sprig of Mistletoe for years but if you do manage to accidentally find yourself under one this year then remember the Government Coronavirus warning that we are not meant to be kissing under it this year.
The tradition says that any woman standing under mistletoe can be kissed and will be dogged by bad luck if she refuses which sort of answers my own question of why mistletoe has fallen out of fashion, that's a court case just waiting to happen due to the current climate of pervy old men preying on younger ladies but it's probably right that it should die out altogether and be consigned to history along with wassailing whatever that is.
Mistletoe comes from the German word for 'Dung' and 'Tang' for twig and goes back to the pagan belief that the white, sticky goo from the berries was the semen of the gods so how did people think Christmas when asked to kiss under a shit stick full of gentleman batter?
One Christian explanation is that was growing on a tree that was used to make the cross on which Jesus Christ was crucified but the Vikings believed that mistletoe had the power to raise humans from the dead and was the property of their God Balder while British pagans believed that mistletoe could keep them safe from evil spirts and would hang it in their homes over the winter Solstice.
Most likely explanation is that it associated with the Roman God of Fertility Venus and was used as part of the Roman Saturnalia fun and games at the end of December which the Christians pasted into Jesus when it tagged it's own guy into their festival therefore meaning more proof, if needed, that Christmas is just a Pagan Festival that the early Christians lazily usurped to nudge out the Roman Gods in favour of their own.
