Our world is one giant community, if part of it is in need of help then will have to help, even if it is only a little bit. If it is possible to help and allow homeless people into a shelter when why isn't it allowed to take a refugee into a shelter?
How would you like it if you were in need of help and everyone refused to do so, and in fact treated you like a piece of dirt on their shoe? It wouldn't be nice, would it? So, it basically comes down to the simple phrase - treat others how you would like to be treated.
Fact is, current vetting processes have failed in Europe, and have allowed dangerous extremists to enter the continent. Until Europe can figure out how to properly vet them, they should not be accepting more. Just look at all the sex crimes and terrorist attacks that have been committed by improperly vetted refugees.
The government has one responsibility and that is to look out for the best interests of the British people. So why would it allow a foreign people who obviously have a difficult time assimilating into its borders? Better question - why would these people of such a different culture flee to a country thousands of miles away where they will be ostracized by language, belief system, customs, etc? Why would they not flee hundreds of miles to a neighboring country where they will fit in? I think we all know the answer if we're being honest.
Germany took in many refugees, and look at what happened to them. They have police with guns everywhere, and they have Islamist terrorists everywhere. And they had so many terrorists attacks in 2017 alone. I think don't take them in. They want to take over western civilization. It's not woman and children coming it's men that want to kill citizens
