Many come for easier lives and seeing social media posts from their friends and family already in the West - easy girls, government handouts, everyone tip toes around you, drugs (don't play like Muslims don't get into drugs either). What's not to like? Every red-blooded male is queued up to get to Europe to be paid, smoke weed and fuck scores of blondes. Sure reality is different in many respects, but the thought of it is enough. These aren't smart people.
On top of that, they hear endless rhetoric in their communities (and from our cuck media) how the west is dying, we are infertile, and we need them to be there. Religious leaders jump on this and use this as evidence that Islam is correct and that God is allowing them to conquer us "without a battle" (despite all the terrorism).
Most of the Muslims I see here seem to be biding their time, producing litters of kids (at the tax payer expense), not working, and little by little taking up more housing, more space, etc. They openly talk about how they will overtake the country in 30-50 years. Their time scale is too small, but they are right, if they are the ones having oodles of kids, immigrating en mass, and natives are PAYING FOR IT, to the point where we can't have kids and homes, then yes, we are finished in a few generations.
These people don't see long term. They don't see that implementing their control would simply turn their western host into another Pakistan/Syria/Shithole, with secretarian violence, the collapse of the rule of law, the death of knowledge (as all education should be 'Islamic'), the destruction of social services and supply chains. In 2 generations, the west will be a fractured hellscape as whites retreat to the countryside and the cities turn into war zones. Of course our cucks will stifle any effort to rectify the situation.
War is inevitable, it is now a question of fighting 5% of the population now, or 30% in the future. I know which is easier.
