Companies exist to make money. They don't actually care about politics except insofar as it makes them money. They'll say whatever they think will make them the most money. Hasbro is staying silent because they don't care either way and saying anything is likely to lose profits.
Seriously, this policy doesn't affect them in any fashion. The middle class are the ones who buy the most toys and have the least children. The people most affected are not consumers. Hasbro has nothing to gain from publicly stating that they support abortion and plenty of profits to lose from middle class conservatives.
While I generally support progressive causes, I agree that the SJWs are doing more harm than good. What we need to do is balkanize the USA into different countries for different political brackets, such as Galt's Gulch, Wymyn's Land, Jesusland, and Wakanda, and fund the mass exodus of people to the new countries that best fit their political views. I wish there was a better solution, but humans have consistently shown that it's impossible for people of differing belief systems to co-exist without attempting to murder each other.
