Baltimore Pride's block party held Saturday drew thousands of people, many carrying signs protesting any further erosion of personal rights.The theme for Baltimore Pride 2022 is "Together Again" as people celebrating in-person for the first time since 2019. People lined the streets Saturday for the return of the Baltimore Pride parade. The hour-and-a-half-long procession spilled into a pride block party, but the energy, excitement and uninhibited celebration also had an vibe of concern.Some people are concerned about U.S. Supreme Court Justice Clarence Thomas' concurring opinion overturning Roe v. Wade that suggests the high court overturn landmark decisions that legalized contraception and same-sex marriage. | RELATED: Roe v.

We are not hurting anybody," said Victoria Lawson, of Baltimore. "What's going on right now is grossly insensitive to human rights and if doesn't stop here. It is so dangerous where this is going to go. What we need is for people to be in the streets," said Jakob Fox, of Baltimore."I'm very disappointed. It's not something that personally affects him or his immediate family. So, it is not right for him to have a say on who should be able to marry who," said Misa Gould, of Baltimore.Thomas wants to do away with the doctrine of "substantive due process," a principle that allows courts to protect certain rights that are not spelled out in the constitution. Friday's Supreme Court decision to overturn Roe v. Wade seized on the idea that substantive due process is not in the constitution.Thomas wrote: "Substantive due process is an oxymoron that lacks any basis in the Constitution ... It's legal fiction that is particularly dangerous ... we have a duty to correct the error established in those precedents."| RELATED: Some fear rollback of LGBTQ and other rights following Roe v. Wade decisionMonumental Supreme Court decisions in the past relied on the doctrine. In 1965, Griswold v. Connecticut established the right for married couples to buy and use contraceptives. In 2003, Lawrence v. Texas established the right for consenting adults to engage in same-sex intimacy. In 2015, Obergefell v. Hodges established the right for same-sex couples to marry."I'm a teacher and I'm thinking about my students and the things they have to go through. They may not have choices in what they want to do in their life. It's really terrifying," said Megan Werden, of Baltimore."Without those rights, we can't solidify our future. This is our child, myself and my wife. This is our child. Without certain rights certain benefits because we are married, we couldn't be where we are today," said Taniesha Wallace-Hardy, of Baltimore.The legal right of interracial marriage also relied on the substantive due process doctrine, but Thomas, whose wife is white, didn't mention that in his opinion.In his opinion, Thomas also wrote that he not only wants to overrule, but revisit the issues to determine whether other constitutional provisions apply.Some legal experts believe Thomas is sending an invitation to state legislators to pass bills that conflict with the Supreme Court rulings on same-sex marriage with an eye toward the high court reversing those decisions.
