Try to remember that Our Lord said that we are not to cast our pearls before swine. I don't even bother getting into conversations about the Faith when people start off with statements like 'you're judging'. They obviously already have their minds made up.
Sometimes in this world, the best you can do is believe the truth and pray. When someone won't even listen to what the Church has to say, as Jesus taught us, treat them as a tax collector and an infidel. That's not to say we are to be mean or nasty, we are just to accord them the proper place in the grand scheme of things. St. Paul the Apostle wrote to Titus (chapter 3, verses 10 and 11) that a person who remains stubborn in their heresy should be avoided completely after we have tried to reason with them twice.
Examples like yours, friend, are just more and more evidence for the power of prayer and sanctity in life. I am not suggesting that you are not living in the state of grace; far be it from me to do so. All I am offering is the idea that WITHOUT a sanctified interior life, and WITHOUT daily, fervent prayer, all we HAVE are arguments, and we are no better than the Protestants.
Believe me, as an 'evangelist' in the Prot world, I used to hear 'you can't judge' and 'everybody got they own sins, so it ain't nobody can tell you what's right or wrong, cause everybody do they own things different' (that, sadly, is word-for-word from the mouth of a woman who claimed that her Prot 'church' taught the REAL truth and she didn't trust me because I came from a different 'church' than her).
The very best thing we can do is consecrate ourselves fully to the Sacred Heart, offer Jesus our lives in union with Our Lady's Immaculate Heart for all the offenses against His love to us, and hear Mass worthily, offering the Holy Trinity that Perfect Gift which satisfies for sin and cleanses us. It's the HOLY people of the world who make an impact for God, not the wise, the learned or the debate-savvy.
Immaculate Heart of Mary, triumph soon.
Sacred Heart of Jesus, have mercy on us.
