The purpose of designating these groups as terrorists is to also stifle freedom of speech. The UK is doing the same thing- labelling groups as terrorists because then it is illegal to express support for them. If you think the Houthis are doing a good thing in preventing supplies reaching genociders, but Houthi is a proscribed terror group, you can be arrested for that. If you do not condemn them, they will attempt to twist this to say you do support them - and you're not allowed to support them by law. This is what Piers Morgan does and the purpose of the 'do you condemn Hamas?' question.

It's to stifle the fact that people in these countries are believing there is a resistance in the Middle East - and not terrorism. And they are absolutely not allowed to think that - it is a big threat to the western empire to have such dissent and freedom of thought from within
