In general people who demonise Thatcher largely agree with her on many policies. They are generally pro EU (she campaigned to remain in the referendum on EEC membership in 1975), they are usually opposed to reopening coal mines, or nationalising BP (or BA or JLR) or making telecommunications a state owned monopoly. To be fair they might favour nationalising utilities and train operating companies, but that is about it. They rarely disagree with her that climate change risks "irretrievable damage to the atmosphere, to the oceans, to earth itself", and are unlikely to want to bring back the use of CFCs.
