Confusion about Perseus

Before taking this class I had read several renditions of the life of Perseus, ranging from serious to complete parody (With Zeus mistaking Danae for a different woman, leaving, then a guard finishing the work while Danae obliviously shouts "Oh Zeus"). While each of the stories is unique, the tale of Perseus and Atlas is the only one depicting the titan being turned into a mountain. What confused me about the story, however, was the opening paragraph of the story.

Acrisius, the son of Abas, born of the same stock as Cadmus still warred upon the new god, still denied Bacchus was a son of Jove--divine. Within Acrisius' city, his walled Argos, the new god was not welcome-even as Acrisius held that Persues, born of Danae, Acrisius' daughter, was no son of Jove, conceived within a godly shower of gold. But soon enough-such is the force of truth--the king reversed himself, accepting Bacchus as deity, and Perseus' claim as just.

What does the denial of Bacchus have to do with Perseus' divine parentage? Does Acrisius simply have a stick lodged up "the one place a dildo fits", or did he just feel like insulting as many gods as he could? I suppose he might've just shared a few genes with Pentheus, but it's still a risky business thumbing your nose at two gods at the same time.
