Posting on social media, external, Scottish Constitution Secretary Angus Robertson said Offord was “not fit for public office”.
Scottish Labour’s Paul O’Kane said: “This just exposes Reform as the nasty party that they are.”
He called on Offord to “make a full, public apology” or stand down as Reform’s leader in Scotland.
Scottish Liberal Democrat MSP Jamie Greene said: “As a gay politician, I’ve been on the receiving end of some fairly unpleasant commentary over the years.
“You almost come to expect it from anonymous trolls on social media. You don’t, however, hear it from the mouths of political party leaders.”
He added: “Sadly, nothing surprises me anymore when it comes to the bile emanating from the mouth of Reform; one wonders how much lower they might sink.”
