Yes, I am a Hindu. This would be easier to deal with all the hindu diaspora, than the specific varnas or varnAsrama. Because, we can easily achieve wider goals by the word Hindu or Sanatan Dharma.

Anyone called Hindu is going to believe in Vedas, else he is of different faith. Ex. Buddhism, Jainism, Sikhs don't accept Vedas as authority. Once a Hindu, he is obliged to believe in the vedic authority.

As per vedas, all first 3 varnas are obliged to learn and practice vedas, but can limit themselves to their professions. Overtime, we all lost some or the other duties. So, we all hindus actually in the same boat. Due to limiting our professions to certain skills mostly learning, teaching, cooking etc, some of us could still practice vaidika karma. I pity those other hindus who couldn't continue their vaidika duties owing to changes in history.

So, also sudras/dalits of current times are interested to take part in such rituals and activities. When Hare Krishnas follow the Hindu tradition, with strict measures as per the Gita, anyone can take up such learning our scriptures their convenient way and follow. Those who cannot rigorously take up vegetarianism or concentrate, can still take part in Yoga, learn smritis like Puranas, Gita, slokas etc.

Those other varnas who were already eligible, can seriously look up lot of wonderful translations, commentaries in the web or through books. Overtime, they would develop conviction and interest. Such people should pursue the upanayam, gayathri japam etc., if not for them atleast for their kids. But, anyone can perform simple altar/archa worship and partake food only after such worship, which would slowly make them take their mind away from habits/addiction to un-vedic foods, past-times, adharmic qualities.

The basic laws of following our Karma Yoga, Jnana Yoga and Bhakti Yoga can be used to address any kind of follower in Hinduism. So, everyone should become pro-active in taking their own responsibility to enhance their spiritual disciplines.
Those who are eligible or had acquired some basic knowledge and practice, should volunteer to help the others sections of Hindus, in sharing such knowledge, through part-time classes, temple discourses etc.

We all can enrich ourselves in making a community that has better self-values and disciplines. The dharma [without the aspects of religion] can also be shared with other faith sections of the society.
