Aquinas held Muslims convertible by argument and opposed forced conversion

Evidence

In the Summa Theologica, Aquinas specifically allows for the conversion of Muslims to Christianity. Only he argued that they should not be compelled to convert. The chief aim of another of his books, the Summa contra Gentiles, was precisely to provide theological ammunition for debates with Muslims, Jews and heterodox Christians. — Robert Irwin, For Lust of Knowing, 596
