Jainism is not simply “against homosexuality” as an identity.

In Jain ethics, the main focus is on:

• Ahimsa (non-violence)
• Brahmacharya / restraint
• Non-attachment
• Self-control

For monks and nuns, all sexual activity is renounced completely.

For lay Jains, the emphasis is generally on responsibility, fidelity, restraint, and avoiding harm or passion, rather than judging a person only by orientation.

So a more accurate way to say it is:

• Jainism is against lust, indulgence, and attachment
• It is not about condemning a person’s inner identity
• Sexual conduct is judged by discipline and ethics, not by labeling someone as “bad”

If you want, I can also explain how Jain karma theory and brahmacharya relate to this.
