At my university, a portion of my dues went to funding BDS efforts (what expenses do they even have?) and I had no clear means to object to this. This was in Canada, but it seems to me perfectly fair to oppose that. That said:
> Most anti-BDS laws have taken one of two forms: contract-focused laws requiring government contractors to promise that they are not boycotting Israel; and investment-focused laws, mandating public investment funds to avoid entities boycotting Israel.
Substitute, for example, any domestic racial minority for "Israel"; does your opinion change?
