You are saying completely irrelevant things now. This has nothing to do with religion.
It can be best described as regional issue. Just like some countries would have supported Ukraine against Russia.
When you bring Islam, you talk strictly about religion. Not some protests. Those protests are against a Genocide, which even human right watch and UN calls as an alarming situation, not to convert, stop, or halt the celebrations of your culture or religion.
The protests are not against the Remembrance Day. Plus, the United Kingdom has a history of taking in refugees. Not only Muslim ones. So, the government know better.
Likewise, we have 4 million Afghan refugees in my country. Their culture is not the same. They also complain about a lot of stuff.
To your surprise, USA has stopped 25,000 Afghanis from going back to Afghanistan:
ISLAMABAD: The United States embassy has issued letters to over 25,000 Afghan nationals under the process of relocation to and resettlement in America and shared their names with authorities in Pakistan, diplomatic and other sources told Dawn.

Please try to understand when I say this:
These problems are created by the Western governments. The immigrants, Muslims or not, are not the real issue. The issue is what these Western superpowers have been doing in other countries (wars).
Take your time to understand this.
Dont mix religion in this issue. I can understand how you feel about this because I have experienced this type of scenario from immigrants, even if they are Muslim, the culture plays a big role.
But, big boys take responsibility for their actions. They dont abandon the people who were affected by the war.
