DAKAR, March 16 - Senegalese proponents of a tougher anti-LGBT law discussed campaign strategy and mobilization tactics with a U.S.-based "pro-family" group that calls homosexuality a public health threat, activists in both countries told Reuters.

The U.S. group MassResistance, known for its work at home pushing legislation against same-sex marriage and denouncing "the transgender war on cultural norms", has advised like-minded African activists for years.
