Mrs Weiss heads a radical settler organisation called Nachala, or homeland. For decades, she has been kickstarting Jewish settlements in the Israeli-occupied West Bank and East Jerusalem, on Palestinian land captured by Israel in the 1967 Middle East war.
Some in the settler movement have cherished the dream - or pipedream - of returning to Gaza since 2005, when Israel ordered a unilateral pullout, 21 settlements were dismantled and about 9,000 settlers were evacuated by the army. (Reporting from Gaza at the time, I saw many who were literally dragged out.)
Many settlers saw all this as a betrayal by the state, and a strategic mistake.
Opinion polls suggest that most Israelis oppose resettling Gaza, and it is not government policy, but since the Hamas attacks on 7 October it is being talked about out loud - by some of the loudest and most extreme voices in Israel's government.
Mrs Weiss proudly shows me a map of the West Bank with pink dots indicating Jewish settlements. The dots are scattered all over the map, eating away at land where Palestinians hope - or hoped - to build their state.
There are about 700,000 Jewish settlers in these areas now and settler numbers are rising fast.
A certain people did the same stuff in Warsaw
They will call it a genocide if white people are dying
Yeah, but now the shoe's on the other foot and it's their time to do a genocide!
