This is the article that the OP's link was a response to:
“We have to treat transgender people with the utmost kindness and respect, and accommodate them legally, but they must not be allowed to displace women’s rights,” Solomons added.
The rabbi from Reading replied to others who were offended saying “Nobody can change sex,” and “He’s a bloke in women’s clothes who uses women’s single sex spaces. Don’t you think that’s problematic?”
In another tweet Solomons said “If rabbis don’t speak up for women and girls then who will? You don’t have to be female to realise that males using female only facilities, males in female sport, males in women’s changing rooms, males demanding female medicine is problematic. Not to mention the gaslighting.”
David Davidi-Brown, chief executive of the New Israel Fund UK, lashed out at Solomons, saying :“This is shameful and an abdication of their pastoral duty and moral leadership,” while calling on Chief Rabbi Mirvis to “demonstrate zero tolerance for this hateful prejudice.”

Earlier in the article it says
“If you think this is a man, Retweet. If you think it’s a woman, like,” Solomons’ tweet read, receiving 625 likes and 3,475 retweets as of Wednesday night.
Which implies 85% agreed that Eddie Izzard is a man.
And yet because one person complained the newspaper ran an article about how it is transphobic to say a man dressed as a woman is still a man.
So OPs article is maybe as much a reply to the slant of the original article.
