I get that, but Islam (emphasis on the religion itself) is something that can infect some people very strongly and cause huge problems in terms of how some people behave.
In that sense, Islam can be analogized to a virus, in that Islam affects over a billion people (the number of professed Muslims), although only a portion of them are particularly susceptible to the proverbial virus that causes them to act in extremely abominable ways.
For that reason, alone, Islam is a scourge, and still needs eradication.
Btw, it's the religion itself that necessitates eradication, and I do not advocate the genocide of Muslims. Love the sinner, hate the sin, and all that.
