This article doesn't explain what Palmer did that is "unacceptable". Americans are free to support whoever they want in an election provided what they do is lawful. I fail to see anything unlawful or immoral about his actions, could someone please explain?
OTOH the action of the accusers (Kokoromi, Polytron, Scruta Games, Tomorrow Today Labs and Augustin Cordes) of initiating discrimination against an innocent party (Oculus) is inflammatory and has no moral justification. Such action will achieve nothing positive: it is an attempt to escalate political differences into the commercial realm and will result in a backlash unless rightfully ignored. Do these people think they have a right to deny others their own freedom of choice?
Trump is being falsely accused of "bigotry, white supremacy, hate". If you are going to accuse someone of those then you must support your accusations with evidence that he espouses those views. Do not let false allegations influence how to vote.
Defending America for the American people is the only discrimination legally permitted at a national level. Denied that right, America has nothing to defend against, so may as well disband it's armed forces, open it's borders and allow any foreign people, religion, ideology or crime syndicate to take over. It's contradictory for anyone to support foreign ethnic groups who want their own homeland like the Kurds in Syria (racial discrimination), or support Israel as a Jewish homeland (religious discrimination), yet believe that American people have no right to their own homeland (discrimination by birthright). Either everyone has a right to homeland (an exclusive place to live) or no-one does.
