On 21 June 2005 experts were called to the Senate to debate the issue . The expert 's opinions were diverse ; some stated that gay adoption had no effect on a child 's development , except for perhaps a higher tolerance towards homosexuality . However , psychiatrist Aquilino Polaino , called by the People 's Party as an expert , called homosexuality a pathology and emotive disorder . Among other assertions that generated debate , he claimed that " many homosexuals have rape abuse antecedents since childhood " and that homosexuals generally come from families with " hostile , alcoholic and distant " fathers , and mothers who were " over protective " toward boys and " cold " toward girls . Prominent People 's Party members later rejected Polaino 's assertions .
