It's not an ad hominem attack to point out that the paper you are promoting was written by someone who advocates for prostitution. It's an important factor in assessing the credibility of research which purports to be evidence led rather than ideologically driven.
I've waded through enough punter babble that I generally avoid following links to potentially dodgy websites.
Professor Neumayer is a professor of Environment and Development at the LSE who writes across a wide range of issues. He does not use his paper to advocate for any political response and, in fact, notes several factors that need to be considered in a political response that are outside the scope of his research. The paper was published in the reputable peer-reviewed World Development journal. Examples of current articles from this journal are:
Why do countries emulate each others’ policies? A global study of renewable energy policy diffusion
China in Africa: Competition for traditional development finance institutions?
The relationship between LGBT inclusion and economic development: Macro-level evidence
Ronald Weizer is a sociologist at George Washington University who writes almost exclusively to advocate for legalising prostitution. The paper you have linked to was published in Sexuality Research and Social Policy, a peer-reviewed journal which is an official journal of the National Sexuality Resource Centre, an organisation which describes itself as a community of gender and sexuality studies researchers, educators, and activists committed to understanding and addressing the intersections of race, class, gender, and sexuality in the pursuit of social justice Examples of current articles include:
Improving the Health of Cisgender Men Who Identify as Bisexual: What Do They Want from Interventions?
Supporting LGBTQ+ Foster Teens: Development of a Relationship-Focused,Self-Guided Curriculum for Foster Families
Gender Identity Nondiscrimination Laws in Public Accommodations: a Review of Evidence Regarding Safety and Privacy in Public Restrooms, Locker Rooms, and Changing Rooms
pie when you comment that "no competent editor of a scientific journal should have accepted" the data in the LSE paper, what are your credentials to justify such a statement?
