Sure, they only have several ministers in the government, Likud politicians show up at settler events, they keep changing the laws to be more in favor of settlers, etc etc...
As for Palestinian settlers, where would those even be?
What? Settlers are totally tolerated and supported by the state. Look at Ariel, it is a fully established town settled almost 50 years ago with a university that operates in every practical way as part of Israel. If you think the government doesn't support them, what would support look like?
