I totally hear you on the Frogs
@Don the Don Point is though that it's not just the Frogs. The reason the Romans conquered Britain back in their day was that so many of the tribes saw a chance to 'get one over' on their neighbours by throwing their lot in with the Spaghetti eaters or simply didn't want to have trouble in their lives and so just accepted the new bosses, Same thing played out when the Angles and Saxons started getting pushy, same again when the Vikings turned up and yet again when the Normans turned up.
DNA studies tell us that, until recent years, the actual genetic make-up of the population of the UK is almost entirely the same population that was here from the end of the Ice Age and so the Romans, Angles Saxons, Vikings and Normans ruled without making much of a genetic contribution which suggests that there weren't enough of them to make an impact on the genetic map of the land so basically they must have been greatly outnumbered by the population they subjugated which, sadly, suggests that a lot of our ancestors were pussies just like the French who simply accepted the new order and went back to their days work.
Sadly we are now seeing an influx of filthy foreign DNA on a scale never seen before in this land and Britain will be changed in a way it never has before unless people fight and push back but I don't hold out much hope of that because history tells us that, for every man willing to fight there are twenty or more, at least, willing to dive into the filth and tell themselves the water is lovely.
