I think this kind of free discussion [2] should not be prohibited.
These are different opinions on academic thought, anyone can discuss them, there is no such thing as damaging prestige.
Therefore, do not talk to Yudin [3] about this matter.
If there are different opinions domestically on such academic issues and any leaders, they should also not be prohibited.
If one attempts to prohibit them, that is completely wrong.
