Nobody called for racial discrimination. Vetting needs to be done based on potential risks posed by connections (possible or confirmed) to a hostile foreign power that is both an autocratic regime and capable of using its influence to coerce people into committing espionage.

Those same considerations would not apply to Taiwanese Americans.

All western countries dealing with China need to consider their security policy carefully and comments like yours poison the well of debate by conflating racial discrimination with legitimate security concerns.
