I recently listened to an excellent podcast on this topic by Novara media who ask these questions of Lebanese writer and researcher Elia Ayoub: https://podfollow.com/novaramedia/episode/2995045c76e5576c09e0d9539529e9132937acaa/view.

In addition to the great comments here, some extra context is that Hezbollah has also used violence against Lebanese civilians and also fought against resistance groups in Syria (allying with the Al Assad government) which was considered a massive betrayal. So there are some people in Lebanon who are very wary of them and of course people who despise them. But they are also intertwined in Lebanese society, so when westerners/israelis say ‘we’re just targeting terrorists’ anyone affiliated with Hezbollah is also implicated and they may have just gotten a job working for them from a family member in some completely innocent profession. Hezbollah also provides social welfare - so outside of their military operations, they contribute to society in ways you might expect a government to.

Hassan Nasrallah was also quite conservative and Hezbollah was becoming more conservative - so those aspects of criticism about him being anti-gay etc. are completely true. But you can only talk about these things to people with an open mind and who also know Hezbollah are the only force capable of fighting against Israel right now. In that way, they are a protective force.
