PHOTOS: Thousands wind through downtown for 45th annual Seattle Pride Parade

For about five hours the 45th annual Seattle Pride Parade wound through downtown, which started at Fourth Avenue in downtown and ended at Second Avenue and Denny Way.

The event's, organized by Seattle Out and Proud, theme this year was a commemoration of two anniversaries: the 50th anniversary of the Stonewall Uprising and the 45th anniversary of Seattle Pride.

"With the help of these historic events, undeniable victories in LGBTQIA+ civil rights have been achieved, including: marriage equality nation-wide, anti-discrimination employment laws in 24 US states and territories, the repeal of 'Don't Ask, Don't Tell,' and acceptance of LGBTQIA+ celebrities, elected politicians, and public figures," Seattle Pride's website said.

But it also acknowledged that the fight isn't over, and that "these advances are only the beginning," something emphasized by recent threats to those celebrating Trans Pride Friday night.

Threats from anti-trans, alt-rights groups, including the Proud Boys, prompted Trans Pride organizers to hire a small private security team and enlist volunteers to help secure this year's event. Protests seemed minimal during the celebrations, however.
