BBC News - B&B ruling: Discrimination a right - Nick Griffin
A court ruled a guest house owner had discriminated against Michael Black and John Morgan when she turned them away.
Mr Griffin said the men had "abused the system to persecute" the Christian owner, after earlier urging Twitter followers to hold a demonstration.
The couple, from Cambridgeshire, said any demo would be a "damp squib".
Mr Griffin is being investigated by police over the tweets published on the @nickgriffinmep account.
'Shocked to hear'
Two of the posts read: "So Messrs Black & Morgan, at [their address]. A British Justice team will come up to Huntington & give you a..." then "...bit of drama by way of reminding you that an English couple's home is their castle. Say No to heterophobia!."
Mr Griffin told BBC 5 live he believed discrimination was a "fundamental human right".
"Mr Black and Mr Morgan have the right to decide who enters their home and who doesn't, as do Christians, and that's what they are taking away," he said.
"Those two gentlemen placed themselves in the public eye and they asked for it when they used and abused the legal system to persecute an innocent Christian couple.
"It's time that the silent majority had people standing up for them so that this relentless bullying of ordinary people by activists and the left-wing judiciary stopped.
"The liberal elite simply won't listen to reasoned argument, so we have to be slightly more forceful. I believe in peaceful direct action."

An earlier tweet on the North West region MEP's account had asked for the couple's address and then said: "We'll hold demo... for rights of all home owners, gays included, to rent or not rent rooms to whomsoever they wish."
