Korn said that every Thai has the right to wear red, which is one of the colours of the national flag.
The red shirts do not have an exclusive right to the colour because all Thais should be proud of the colours on their flag, he said.
If the red shirts are true advocates of justice, then they should not discriminate against others who are seeking true justice and not the pseudo-advocacy that cites reconciliation as a guise to whitewash former prime minister Thaksin Shinawatra, he said.
A number of Democrats, including Thepthai Senapong, put on red shirts in a bid to deny the red shirts from monopolising the colour.
