So if the government had a major problem with the a free speech, its doing a pretty good job of not showing that.
In the Commons, the argument hasn't been against the humanitarian crisis faced. However, the situation is more complicated when Hamas and a significant portion of the Israeli government want to eradicate each other and end any hopes of the two-state solution, and act accordingly violent.
The situation with Palestine Action being made proscribed also isn't because of their beliefs, but their actions. You can't commit criminal activity like destruction of property and violence against people for political reasons and not come under the remit of anti-terror legislation. The same has happened to environmentalist groups that have taken their actions too far, and for groups like the IRA pre-Good Friday agreement.
I could walk to my local town centre with a placard for either saying: "Stop Genocide in Palestine" or "Down with Hamas" this weekend and not be arrested.
You might "just" get threatened with arrest:

Or you might get arrested:

There are many similar ones, but they are now much harder to find due to the hundreds of arrests over Palestine Action.
This has been a common theme after the proscription: The police has repeatedly abused the proscription to go after people expressing opposition to Israels actions in Gaza, without mentioning PA.
The excuse for that is that the Terrorism Act is not limited to making direct, overt support illegal. Section 13 makes it illegal to wear an item or clothing or wear, carry or display an article in such a way or in such circumstances as to arouse reasonable suspicion that he is a member or supporter of a proscribed organisation.
This has multiple times been interpreted by the police as justification for threatening arrest over expressing support for Palestine, and the government has done nothing to stop the police from drastically overreaching in this way.
