الجواب وبالله التوفيق
When the desire to achieve something is true then the person gives sacrifice of their time, money and relationships for that achievement. Therefore, such individuals who have the true desire to attain the knowledge of deen, then even the age of 60, with more than 2 children and work during weekdays does not stop them from coming to the madrasah on the weekend to seek ilm-e-deen. There are other such individuals who do not have access to a madrasah in their locality, but this does not stop them from enrolling in online madaris and academies to seek the formal education of deen. Since they do have the true desire, it makes them perform these sacrifices. However, if the individual does not want or desire by themselves, then there are a thousand excuses in not pursuing something.
If an individual does not stop going to the mosque due to politics, then this politics cannot be considered as an excuse in gaining ilm-e-deen from the local ulamah kiram. However, if someone does not go to the mosque due to the politics, then that is a matter full of distress and sorrow.
