1. Correct, there is no constitutional right to immigrate.  However, once you allow someone to immigrate or seek asylum, they have constitutional right to due process.  
2. Trump's ban is much broader than Obama's and has been hastily implemented, i.e. DHS and ICE given incomplete and conflicting instructions.
3. The executive order has an exemption for religious minorities, i.e. christians, thats a religious test.
4. That's paranoid blather.  Radicalized muslims are a much smaller subset than muslims that have no intent to harm americans.  We need to discern between these two even if it feels better just to lump them all together.  Its like in war where you need to distinguish between combatants and non-combatants even if it would be easier just to kill them all.
5.  If you change "muslim" to "terrorists" I would agree.
6. Correct but you are basically repeating yourself (see #1)  
7. More paranoid blather (Well, you said 6 again but we know you mean 7)
