Law is always subject to interpretation and as imperfect as it sounds it is better than no law at all. And I'm not talking about hate speech specifically. Using this as a tool to silence opposition is possible and made easy in countries that do not value and nurture independence of institutions and have rampant corruption, often countries with authoritarian leadership. UK is not exempt of criticism, it would be unhealthy not to, but comparing Russia/Putin with UK/Starmer makes it evident that you are more concerned by pushing a political agenda that by facts and reason.
