John Franson/Canadian Press Conservative MP Kerry Diotte speaks after winning Edmonton Griesbach on Oct. 19, 2015.

An Edmonton MP is threatening to take a number of Twitter users to court after they called him "racist," but they're not backing down. Edmonton writer Bashir Mohamed is one of them. He received a letter from a lawyer representing Conservative MP Kerry Diotte on Monday, demanding he remove a series of tweets from last week. In the social posts, Mohamed wrote that "Kerry Diotte is a racist," pointing to the MP's relationship with white nationalist Faith Goldy, and stated that "he is incapable of helping the people he represents." Mohamed refuses to delete the tweets and said he's willing to fight the Edmonton Griesbach MP in court.

Courtesy Bashir Mohamed Edmonton resident Bashir Mohamed says he won't remove his tweets that call MP Kerry Diotte "racist."

"If this was years ago, if I was still in university when this happened, I would've deleted the tweet, but now I realize that I should stand up for my free expression and things that I truly believe in, which is that a politician should be accountable to people he endorses and the people he takes photos with," Mohamed, 23, told HuffPost Canada.

On Nov 5 2018, Kerry Diotte - Member of Parliament for Edmonton Griesbach - sent me legal notice regarding tweets I made about him and his support for Faith Goldy - a white nationalist. They gave me the deadline of Nov 7, 2018 to remove the tweets This is what followed #cdnpolipic.twitter.com/FejP6GSbhw — Bashir Mohamed (@BashirMohamed) November 9, 2018

At least three other people, also in their early 20s, received a similar letter from Diotte's lawyer. Haiqa Cheema, 22, has left up her tweet about Diotte from Oct. 24. She and two others declined to comment when reached by HuffPost.

@KerryDiotte has to be one of the most racist MPs sitting in parliament. I expect student leaders to exercise better judgment when engaging with politicians. There is a fine line between being "non-partisan" and being complicit https://t.co/2hJ4VSyyQS — Haiqa Cheema (@haiqa_cheema) October 24, 2018

"You know such statements are inflammatory and untrue," said the letter addressed to Mohamed and signed by lawyer Arthur Hamilton, who also represents the Conservative Party of Canada. "In the absence of immediate action to remedy this circumstance, and effect a full retraction ... Mr. Diotte will initiate proceedings without further notice to you." Hamilton and Diotte did not respond to HuffPost Canada's requests for comment. U of A event sparked tweets The controversy began when Mohamed expressed disappointment that University of Alberta students had spent time with Diotte at an event in late October. Mohamed posted photos from Diotte's Twitter account that show the MP and Goldy together at two separate events in February 2017 and May 2016.

Kerry Diotte is a racist. It's very disappointing to see student reps cozy up with a racist who openly associates with white supremacists such as Faith Goldy. Someone who he has refused to distance himself from and who he claims made 'media great again'https://t.co/pPGt68DTFN — Bashir Mohamed (@BashirMohamed) November 3, 2018

Diotte's tweet from 2017 came weeks after a gunman opened fire at a Quebec City mosque, killing six people. Goldy worked for alt-right Rebel Media at the time and was widely criticized for propagating conspiracy theories that Muslims were responsible, rather than a white Canadian man, as was the case. Alongside the photo of Diotte and Goldy, the MP's tweet appears to compliment Goldy's journalism.
