They fix the MTA before even thinking about raising it

Yes, that is correct. Philosophy has never been a purely objective pursuit of truth, but rather it is an ongoing dialogue and investigation that is influenced by the cultural, social and historical context in which it is practiced. Philosophers are influenced by their own experiences, beliefs and biases, which inevitably shape their perspectives and understanding of the world.
Furthermore, the philosophical concepts and questions have often evolved in response to historical and cultural developments, and different cultures have developed distinct philosophical traditions. The ideas of Western philosophy, for example, are deeply rooted in the culture and history of ancient Greece, while Eastern philosophy has distinct concepts and traditions rooted in the culture and history of China, India, and Japan.
This doesn't mean that philosophy lacks objectivity or value, but it's important to recognize that philosophies are products of their time, place, and culture and that they are subject to change and revision over time. It is worth studying different philosophical perspectives to understand how the diverse cultures and societies have shaped their philosophies and the questions they were trying to answer, this provides a richer and more complete understanding of the subject.

It is true that philosophy, like any other field of study, is influenced by the cultural and historical context in which it is practiced. Philosophers are human beings and they are deeply influenced by their cultural, social, and political surroundings, which can shape their thoughts and beliefs.
Philosophical ideas and theories have developed and evolved over time, and these changes have often been influenced by the cultural, social and political context of the time. Many philosophers have been critical of the dominant cultural, social and political ideologies of their time and have sought to challenge and question them.
Furthermore, different cultures have developed different philosophical traditions, some cultures have had more of a tendency towards metaphysical and spiritual beliefs, while others have had a more rational and empirical approach.
It is important to acknowledge the cultural perspective and context of philosophy, as it can give a better understanding of the evolution of certain ideas, the motivations behind them and the context in which they were formed.
Philosophy as a discipline is ever-evolving and today many philosophers are actively working on trying to remove biases and prejudices that might be present in the field, and this includes also looking at how culture, society and politics might be influencing their own thoughts.
