From the Daily Mail article:
Linehan, 57, has shared the tweets which he says police arrested him over. One from April 20 said: 'If a trans-identified male is in a female-only space, he is committing a violent, abusive act. Make a scene, call the cops and if all else fails, punch him in the balls.'
A second tweet, on April 19, was a picture of a trans rally with the caption: 'A photo you can smell.' The third was a follow up to this tweet which said: 'I hate them. Misogynists and homophobes. F* em.'
This tweet is what @Christinapple is referring to as 'incitement to violence'
As PP have stated, the double standards are astonishling
