People who sympathize with our enemies should not be allowed into our country . If visa holders are shown to do so then we should strip them of their visa and deport them .
And yes Palestine is our enemy along with Iran , Russia , China . If you sympathize with the governments or the causes of those nations then we should not allow you into our country .
You don't have to be Muslim to understand India is a bigger threat than any of those countries.
Ok then find a politician who wants to implement such a policy and get them elected.
