DETROIT -

People everywhere on social media Thursday are seeing purple. It is part of a national 'Spirit Day' movement to take a united stand against bullying and to show support for lesbian, gay, bisexual and transgender youth.

Even the Detroit Tigers changed their Twitter profile picture (with the traditional blue and orange) to reflect their support of the cause.

Tigers fans will be able to learn more about Spirit Day at Comerica Park Thursday night during Game 5 of the American League Championship series against the Red Sox. There are going to be images flashed on the scoreboard and an announcement made to fans about how they can get involved in the cause.

Not every Detroit fan is happy about it. The Detroit Tigers Facebook page was riddled with comments from fans saying the team is supporting "immoral behavior" and "Now I have to unlike your page".

Support of the cause didn't go over well on the Atlanta Brave's facebook page - with several fans threatening to boycott the team.

'Spirit Day' began in October 2010. The name comes from the purple stripe of the Rainbow Flag.
