Tony Perkins does not represent the views of many people. His ignorant comments about homosexuality do nothing to help people of faith or the general population. Many people are glad to see his own words blow up in his face when his home is damaged by the natural disaster of flooding.
Yes, Tony Perkins' description of biblical proportions is too provocative after his previous anti-gay remarks. It makes little sense to believe that there being gays has anything to do with why homes were flooded. The flood has nothing to do with gays. It is a natural disaster. His statements are stupid.
Mr. Perkins has been accused of making statements in the past that have been seen as inflammatory to the LGBT community. However that is a separate issue; he was describing a catastrophe he was experiencing. The phrase "biblical proportions" can be used, as in this case, in a secular manner as hyperbole to describe an actual devastating flood.
No, his description of "biblical proportions" was not inappropriate. Saying that floods are of "biblical proportions" is a common expression used after a devastating flood, referring to the story of Noah's Ark. While it might have been somewhat conceited of Perkins, he did not use it in a homophobic manner. Also, many people oppose gay and trans rights on religious grounds, so it makes sense that an anti-gay lobbyist would use religious rhetoric in other areas of his life as well.
