Signing letters of support for boycotting intellectual institutions, and academic cooperations is essentially anti-intellectual. The last twelve months were just an opportunity for many people sharing more or less loudly radical anti-Israel opinions to raise them at the level of open statements. In a way, it is a good way as it offers to people the chance to show what they think. Psychologically and not only, it releases them of the pressure of saying - or rather not saying at all - things they were thinking about.
The list shared by LitHub, which is slightly growing by the day, appealing for a boycott of Israel cultural institutions, was created around voices like Sally Rooney who already announced very proud at the beginning of the year that she does not allow her books to be translated into Hebrew. (Nothing about Russian, or other languages of countries where people are really opressed by their own governments). Some of the people who signed are famous in the literary world for their works, some for being vocal. Some are writers or poets, some are just translators. Some are just names that hopefully will sign one day more than just a protest for a far away cause they are trying to get advantage of from the comfort of their lofts. Some authors I may know, some I really like, some are just as toxic as what they claim they believe in.
I think is everyone´s right to have an opinion, also a wrong one. We expect too much from intellectuals, but as history showed already, they are humans as everyone of us. They need to pay bills, sign political protests in the hope to get some points for their portfolio always in the making. Totalitarian regimes were supported by intellectuals, created by intellectuals, fuelled with ideological content by intellectuals. Sometimes they have no idea what they are getting into, but sometimes they are fully aware as they are widespreading lies and old libels.
This letter, in addition to many other moves that happened since 7/10 do not talk about peace, do not want to build bridges with intellectuals in Israel who do share critical points of view towards their government, as shared in their books and public statements. The letter is just building a wall, aimed at pressuring the public opinion in a direction that does not have nothing to do with being an intellectual. Also, not with intelligence, in the genuine sense of the world.
I would have been really empathic to the interest of the signatories if they will be so acribic vested in, for instance, cutting any cultural ties with Russian institutions - as we speak, Russia is attacking Ukraine; Chinese cultural institutions - Uyghurs are opressed, intellectuals are not free, the authors allowed outside do share propaganda messages; Islamic Republic of Iran - who brutally murdered intellectualls, among many other things against freedom of thinking and women rights; and so on, and so on...
In free countries, people are free to be wrong and long for propaganda vitamins and wear keffiyeh or for anything they wish for some or the others. But also in a free country, they may not be out of criticism for their childish or well-funded/intentional misleading investment in a cause obsessively taking ovet any others, with a not so humanistic intention.
