You ignored my explanation about crimes committed during national rioting. Connelly was charged with;
An Act to abolish the common law offences of riot, rout, unlawful assembly and affray and certain statutory offences relating to public order; to create new offences relating to public order; to control public processions and assemblies; to control the stirring up of racial hatred; to provide...

"A person who publishes or distributes written material which is threatening, abusive or insulting is guilty of an offence if—
(a)he intends thereby to stir up racial hatred, or
(b)having regard to all the circumstances racial hatred is likely to be stirred up thereby."
She said "mass deportation now, set fire to all the ◊◊◊◊◊◊◊ hotels full of the b******* for all I care... if that makes me racist so be it". That was during spreading national rioting which included the setting fire of hotels with immigrants in them.
What else could a lawyer do, when she admits to the tweet, it specifically advocates racial violence, when there was rioting targeting immigrants? Can you provide a reasonable defence? The Act provides a defence;
"In proceedings for an offence under this section it is a defence for an accused who is not shown to have intended to stir up racial hatred to prove that he was not aware of the content of the material and did not suspect, and had no reason to suspect, that it was threatening, abusive or insulting."
She knows she is being racist and is calling for violence based on her racist beliefs, so she does not have that defence. You might try she has freedom of speech to stir up racial hatred and call for specific attacks on specified people, that was actually happening, but you would get nowhere. No lawyer would try that and he was wise to advise her to plead guilty early, apologise and get a lesser sentence.
