An SNP 'supporter' called former justice secretary Humza Yousaf a "racist piece of s***" in an abusive email.
John Conquer, 65, of Kilmarnock sent the message to a constituency office in Glasgow's Cardonald on April 11, 2020.
Conquer dispatched the email after viewing Canadian right-wing outlet 'Rebel News' video commenting on Mr Yousaf's speech to the Scottish Parliament about a hate crime bill.
The email said: "Watched the latest Rebel News video on YouTube, you are the main subject.
"Only because you are a piece of racist scum.
"We don't need people like you in Scotland stirring up racism in Scotland you racist piece of s***.
"I will share the Rebel News video to everyone to show what a horrible b****** you really are.
"Signed, John, Glasgow."
The video "Ezra Levante Rebel News Agency" - which has been viewed 190,000 times - was the email's heading.
The matter was reported and Conquer was traced by police and arrested.
Conquer told officers: "I've got a funny feeling this might have something to do with my political beliefs.
"It's the only thing I can think of because I don't do anything."
Conquer pled guilty today at Glasgow Sheriff Court to behaving in a threatening or abusive manner.
The charge was "racially aggravated."
Graham Cunningham, defending, told the court that Conquer is an "SNP supporter" who has health problems.
Sentence was deferred pending background reports until next month by Sheriff Kevin McCarron.
Conquer had his bail continued meantime.
