Second link is Trump pointing out exactly what the first article says! That X place wants to run a casino, but can't get legal permission. So they go to Indian tribes to get the legal part bypassed. It hardly seems bigoted to point out this is just exploiting a legal loophole.
It does everyone a disservice to so lightly throw around these words. If I were to start calling every panhandler/beggar that bothers me "assault", people would discount it. Same with all these accusations - they are losing their impact and people will start ignoring it. If Trump and the like are to be defeated, his opponents are going to have to come up with more substance instead of yelling "bigot".
(I'm in Guatemala, and some people here realise how good Trump will be for them. By blocking illegal Mexican immigration, if immigrants are needed, it'll open up more legal pathways for countries that aren't Mexico.)
