I disagree, Mary.  Trump's ideological purity test is an excellent idea and needs to be expanded.  I want to see each U.S. citizen be required to answer the following questions correctly:  

Are you a Christian?  Do you believe that women should be imprisoned if they have an abortion?  Should all (white) Americans be required to carry a firearm at all times?  Are rich people rich because they're simply better than you?  Is climate change a hoax?

If you fail to answer 'yes' to any of the questions you will be rounded up and sent to re-education camps in Texas and Oklahoma.
