The "Identify hate groups on GuideStar" is a free Chrome add-on developed by Tom. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

This add-on aims to provide users with information about hate groups that have been identified by the Southern Poverty Law Center (SPLC) on the GuideStar and CharityNavigator pages. It should be noted that this add-on is not affiliated with GuideStar, CharityNavigator, or SPLC.

GuideStar recently added extra information about charities associated with hate groups, using data from SPLC. However, some conservative groups protested this move, arguing that not all groups opposing same-sex marriage should be labeled as hate groups.

The "Identify hate groups on GuideStar" extension restores this information on the GuideStar platform. While users are encouraged to visit the SPLC links and make their own judgments, the add-on provides additional information for a more informed decision-making process. It aims to shed light on groups that have viewpoints deemed as unquestionably hateful.
