What contradiction does the Palestinian bookseller identify in Israel's claims about its society?

The Palestinian bookseller identifies a fundamental contradiction between Israel's claim of being a liberal democracy while simultaneously banning books and suppressing Palestinian cultural identity. He emphasizes that these two things 'cannot work together' - a nation cannot genuinely call itself a liberal democracy while engaging in censorship. He explains that Israel sees Palestinian cultural expressions as a 'huge risk' and is actively working to 'crush' spaces where Palestinian cultural identity is celebrated. This systematic suppression of cultural expression through book bans represents a direct contradiction to democratic values that supposedly protect freedom of expression and cultural diversity.
