Although there are no options attached we can say the following.
How are various minority communities gaining political power?
The way minority communities are gaining political power is through organizing to formally express their opinions through advocating social issues concerning the necessities of these communities.
They are formally organized and using social media to express their messages, inviting people to join, donate, and participate in their political causes.
This way, they are strengthing their relationships and increasing the number of members that are actively participating. This allows them to have a specific weight or political presence that can pressure the government or other instances. That is the way many African American, Hispanic, Asian, and LGTB groups have increased their presence in US politics.
