Van Langenhove is the founder and leader of the far-right Flemish nationalist youth organization Schild & Vrienden [nl].

Van Langenhove and Schild en Vrienden members disrupted pro-immigration activists at Gravensteen castle calling for more humane refugee policies.

[10] In April 2021, Van Langenhove started a YouTube channel called Kies Dries where he discusses current events and politics.

[11] In 2017, Van Langenhove set up a youth movement called Schild & Vrienden [nl] which shared right-wing memes and participated in political demonstrations.

[13] As a result of the investigation Van Langenhove, who denied involvement in sharing content in any of the groups, was temporarily suspended as a student by the university of Ghent.

[15] However, Van Langenhove submitted a request of recusal against Serlippens citing political bias that she had previously liked and retweeted a poem on Twitter referring to him and former immigration minister Theo Francken as "rancid" and "fascist."

In September 2021, Van Langenhove's lawyer requested that certain investigative actions against him be annulled on grounds of bias and breach of privacy.
