Overview
Fighting Duryodhana is Dharma. Fight Duryodhana in the way you can, that is swadharma. Dharma is the same for everybody, but swadharma varies according to your physical, social, temporal conditions.
But remember that swadharma can never be in contradiction of Dharma; swadharma will always be something within the ambit of Dharma.
Bhagavad Gita
स्वधर्ममपि चावेक्ष्य न विकम्पितुमर्हसि । धर्म्याद्धि युद्धाच्छ्रेयोऽन्यत्क्षत्रियस्य न विद्यते ॥
Even considering your own duty you should not waver, since there is nothing else better for a Kshatriya than righteous battle.
—Shrimad Bhagavad Gita, Chapter 2, Verse 31
