"当你说任何一个思想体系是神圣的，无论是宗教信仰体系还是世俗意识形态，当你宣称一套思想不受批评、讽刺、嘲笑或蔑视的影响时，思想自由就变得不可能。"

Simplified Meaning:

When you treat any set of ideas as untouchable and beyond questioning, whether it's about religion or any other belief system, it stops people from thinking freely and expressing their opinions. Imagine you have a rule in your house that nobody can ever say anything bad about broccoli. Even if someone doesn't like broccoli or thinks it's overcooked, they can't speak up. Over time, everyone pretends to love broccoli, and any real discussion about its taste or preparation disappears. In a larger sense, like in a community or country, if certain beliefs can't be criticized, people stop thinking for themselves and just accept what's given to them. This lack of open discussion stifles creativity and progress, making it hard for new, better ideas to emerge. To live more freely, it's important to allow all ideas to be discussed openly, even if it means challenging the ones we hold dear.
