None is opposing the idea of tougher migration policies that at the same time prohibit illegals and facilitate the process for legals. That is the ideal and that what has been proposed by many candidates, just check the Miami democrat debate in which both Hillary and Bernie proposed their takes on that ideal. However what Trump considers tougher immigration policies are just absurd, its just like using a canon to kill a mosquito. The idea of a wall on itself is absurd and does little to stop the remaining 50% of illegal immigrants.
But I'm getting Off topic, the reason I consider Trump racist (according to law in bolivia biased attitudes(discrimination) towards people for their nationality is considered racism so bare with me on this) is due to one specific point that he made in his speech:
- Claiming that only mexican illegal inmigrants are rapist and the usual slur he spits from his mouth, which implies that MEXICAN illegal inmigrants are the ones that commit more crimes; which has been disproved
