No it isn't. The border wall is an idea rooted in racism. Look at Trump's nonsense about rapists and murderers. The immigration ban is a policy rooted in racism. Look at Trump's nonsense about Muslims cheering during 9/11. Do you notice a pattern how support for these policies go hand-in-hand with racist comments? That's because these policies are inspired by the idea that white people are superior to non-white people. It's not hard to tie Republican economic and domestic policies to racism either if you're willing to go one step below the surface.

Then they need to stop supporting it. Voting for racists or for people who stand by while racist policies are enacted is equivalent to supporting racism. This is simply calling a spade a spade. Republican policies are racist and supporting Republicans means supporting racism.
Calling /all/ of these people racists is extremely divisive and also blatantly untrue. Doing so does not win you elections and it doesn't move the politics of the US forward. All it does is make you look unreasonable to anyone intelligent and maybe win you virtue signalling points with Facebook-focused liberals. It also demeans the term "racism". Can we focus on the ACTUAL racism that's occurring within our current administration without painting large swaths of the voting population with an unfair brush?
Also, can you please take the time to breath deeply and realize that Donald Trump is not the only politician who was voted into office on behalf of the Republican Party?
This is patently untrue and statements like these are not helpful to the overall political situation that you're upset about. Demonizing your opposition in your rhetoric is divisive and causes reasonable people to shy away. One of the reasons the Democrats lost the elections almost across the board in 2016 was because of their insistence on divisive rhetoric. To win elections you need the reasonable middle that are registered to neither party, this voting bloc overwhelmingly voted Republican in 2016.
The conservative ideology is not racist. In fact, strong conservativism was a primary hallmark of support for things like the civil rights movement. Unfortunately the Republican Party is more authoritarian and corporatist than conservative these days. Regardless, many people are registered as Republicans who abhor racism and bigotry.
