Senate Democrats charge Republicans with creating a license to bully
There are three quotes from Democrats, none from Republicans. A full explanation of the Democrat's position, no rationale as to why the Republicans voted this way.
My suspicion? It is to protect the free rights speech of children. What is likely, reading between the lines of the story, is that the bill the Dems wanted would have made it a crime for a student to say publicly that he/she disagrees with the homosexual lifestyle. Maybe make illegal any comment about race, gender, class, country of origin, etc.
What the author of this news article is likely not saying is the Democrats were probably trying to push through another of their thought crime laws.
But we can only guess, reading this article.
