Hurricane Harvey : Why Some Are Refusing to Donate for Relief

Charlie Hebdo Cover, Charlie Hebdo 

I was having a conversation with someone about Hurricane Harvey and the person I was chatting with blatantly said that they had zero intention of donating to Houston. I was told that Texas has an enormous amount of racism within it, a high number of Trump supporters, and they just will not be donating.
After googling my way around the net, I came to find that there are a few others who share this decision albeit for different reasons. The Women's March wanted to focus monies raised for the relief of minority ethnic groups. A co-worker of mine stated that they would rather contribute toward relief efforts for the stranded animals in Texas. I found another article about yet another woman who had more interest in the animals and less interest in Trump Supporters.
Is this a choice? Reverse racism? Both?
As Americans, it would be ideal to help our fellow man. We often dabble in the affairs of those overseas, however with the political climate as it is since the inception of the Trump Administration the definition of "American" is becoming quite subjective. I think it's foolish to believe the nation hasn't always been this divided, I just believe the division is far more apparent now that many people feel comfortable expressing views once suppressed.
The sad part of all is this is that we aren't different. We are all a part of a human race. However, that race has been dissected into sub-categories, classes, political parties, etc. Now we are so divided that the devastation of a natural event is looked at by some with the harsh views similar to a Charlie Hebdo cover.
I try hard to respect all views so long as they are stated respectfully however, it's becoming more and more difficult to feel a part of a nation that is so divided. I'll also say that I haven't donated to every relief effort presented be it forgetfulness, lack of excess funds, or even lack of being emotionally moved. I've never taken a stance NOT to help. However, when a wall is being discussed to keep people out, some who are in your own family...  I suppose I could understand why people are creating yet more boundaries between them and "the others". "We", is no more.
