Is Islam pretending to coexist?

Is Islam pretending to coexist?
In the past Islam coexisted fine because their delicate eco-system like religion did not feel threatened by blatant sex be that gay or out of wed-lock. When we non Muslims talk integration we fail to see that integration means for them a whole different thing. It is us who should integrate their faith whether by conviction or force.
On the other hand some Muslims have secretely joined our ‘’dark side’’ enjoying things that are not halal. They can’t apostatize so easily as one of us may . They can pay a hight price. The feel pressure from everywhere including embers of guilt.
In either case the way out is often is to turn against the satanic west and hope Allah will forgive them and take them in Paradise if they give their lives taking some of ours demons along. This could be a good explanation for people being radicalized and why their brothers in faith don’t know about it.
Some guy in Texas -whose honestly I can’t remember now- has calculated in a a number of videos the level of pressure Muslims exert according to their percentage in society. That is a fact and my theory would explain that too without the theory of conspiration which talks of concealed jihadism gradually developed as derived from some Koran versicles.
My writing is more approximative diagnosis than treatment but the result surely should be our preservation of sex and religious freedom including that of being an atheist. However I may expect not ideas but sour responses at the very least.
