You are missing that the intent is to censor the scope of acceptable discourse, the justification given can have different paths (protect, kids, protect migrants, protect trans people) but the intent itself is the same. The laws are effective and their objective is to censor speech and behaviour, the fact you agree with the censored speech doesnt take that the state deems some speech deserving to be censored. The issue is that democracies go in a oscillatory manner and the speech you deem bad will some day became part of the institutions, and then they will have the same power to censor what before was allowed.
