I support the President's position because I object to erring on the side of pandering to cowardly racists, and because there has been no demonstrated link between allowing the resettlement of refugees and seeing an increase in terrorism.
I think the President is adamant to accept refugees in the wake of the Paris attacks because the attacks demonstrate the horrors these people will continue to face if we don't help provide them safe haven.
Here's a pretty good video on the topic:
