A matter of semantics for some. Islam is that religion which Muslims practice. It is the religion of Mohammad their prophet.
Perhaps, but we're not at that point at all.
Some Muslims aren't Islamists. Some are. However, they are not evenly distributed across the globe.
If you were forced to spend the rest of your life in a predominantly Muslim country of your choice, would you rather live in Turkey or Saudi Arabia? Senegal or Pakistan? Dubai or Somalia? Would you really say that the differences between them are "word play"?
