Ugandan President Yoweri Museveni has written a letter expressing his doubts about an anti-gay bill approved by lawmakers.

In his 8-page letter, published Friday in the Kampala newspaper Daily Monitor, Museveni explains why he is reluctant to sign the bill into law.

The bill, unanimously approved by lawmakers last month, four years after its introduction, provides for life imprisonment for the crime of “aggravated homosexuality” and outlaws the promotion of homosexuality.

In his letter to the speaker of parliament, Museveni calls gays “abnormal” because “a normal person was created to be attracted to the opposite sex in order to procreate and perpetuate the human race.”

“What do we do with an abnormal person? Do we kill him/her? Do we imprison him/her? Or do we contain him/her?”

Tamale Mirudi, the president's spokesman, told the AFP that Museveni is opposed to gay rights but does not believe gay people should be treated as criminals.

“What the president has being saying is that we shall not persecute these homosexuals and lesbians. That's the point,” Mirudi said.

“Let us cure the economic conditions so that we rescue our youth and, then, see how to deal with the few abnormals that may be there among us,” Museveni wrote.

The president advised Uganda's parliament to study the issue.

It appears Museveni is sitting on the bill because lawmakers have the votes to override his veto.
