A more appropriate analogy would be someone could take your signs down if you put them up in their yard.
Not really, because their yard is not a domain set up
specifically for everyone to place yard signs there.
Twitter is a domain set up for the public to express
their opinions.
Try telling Blacks, Hispanics, or homosexuals they can’t
make purchases at a super-market, and see how long
that lasts.
The majority have civil rights too.
