I think I’m general you are right, the south is more Conservative. This ist probably because the south is rich. Most Money in Germany is produced in Bavaria, Baden-Württemberg (where I live) and Hesse. They cling to their money very badly, hence the conservative mindset. That being said, there are very progressive hotspots. The Capitals for example (Frankfurt, Munich, Stuttgart) are very open for differing views and Social political ideas. But you can go even better. If you look for City’s with high Student concentrations you go more and more left. I am from Tübingen and this place hates conservatives. Anti LGBTQ Ideas must fear for ther physical protection. The same thing will be true in Freiburg and Konstanz in BW but I am sure there are places in the other two country’s aswell. Can you give us an estimate where to go and how progressive the people should be? Then we will a place, I am sure.
Fabric is - as you know - not made out of a continuous material but rather fibres. These fibers allow for movement up to the point were the network is in tension. This tension is the result of bonds. While the fibre itself relies on covalent bonds of extreme strength the bonds between different fibres are way way weaker. So weak that they “feel” temperature. Also a polar solvent like water weakens these bonds significantly. If you iron fabric while it is laying flat, the fibres rearrange to minimise tension. The new arrangement hardens out while cooling. The new arrangement prefers a flat structure. That way it looks flat on your body.
