Pride peeps: Elected officials and actors were out in force at Sunday’s Pride March. Ian McKellen, sporting an honorary rainbow sash, was one of the grand marshals this year. Who knows? Maybe he’ll make it a “hobbit.” Councilmember Corey Johnson was having a good time at the March, which is never a drag for him…though it definitely always is for others. Meanwhile, state Senator Brad Hoylman — with his husband, David Sigal, and their daughter, Silvia — was out, proud and also loud, thanks to his electric bullhorn.
