"My cousin and her partner, and my Aunty and her partner are some of the most kind, caring & loving people I have ever had the pleasure of knowing. To think that I play against someone that says they'll go to Hell for being gay disgusts me," Weber added.
Fellow halfback Tj Perenara, is the first high-profile player to come out in support of Weber's comments.

Meanwhile Folau will not be sanctioned by Rugby Australia (RA) for his controversial stance on homosexuality.
RA boss Raelene Castle has been satisfied by a column in which the Wallabies star reiterated his religious convictions after claiming gay people were destined for hell unless they repent their "sins".
Folau, whose contract with Rugby Australia expires at the end of 2018, reinforced his belief that homosexuals were destined for hell based on Biblical text.
"I was asked a question by somebody about what God's plan is for gay people," Folau wrote.
"My response to the question is what I believe God's plan is for all sinners, according to my understanding of my Bible teachings, specifically 1 Corinthians 6: 9-10:
'Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor the drunkards, nor revilers, nor swindlers will inherit the kingdom of God.'
"I do not know the person who asked the question, but that didn't matter. I believed he was looking for guidance and I answered him honestly and from the heart. I know a lot of people will find that difficult to understand, but I believe the Bible is the truth and sometimes the truth can be difficult to hear."
