Impose not on others
I think that as a Muslim, the writer has every right to wear T-shirt and long pants instead of bikinis in a hotel swimming pool but she shouldn't stop non-Muslims who have no qualms of wearing bikinis from doing so.
Her statement that "I am offended when I see tourists and westernised Malaysians wearing revealing bikinis and swimsuits, not only in hotel pools but also public beaches" is intolerant, and is no more justifiable than tourists and westernised Malaysians expressing offence or ridicule in seeing her swim with T- shirts and long pants.
The writer should understand the meaning of tolerance. What is appropriate for one's religious beliefs should be observed by oneself but not extended or imposed on others who have no such similar beliefs.
Just like if the writer does not take alcohol or pork because they are haram (forbidden) in Islam, should she feel offended by non-Muslims doing otherwise?
As for the Terengganu hotels building two swimming pools, they will now have to build three: two for segregated sex of Muslim faith and one more for tourists and westernised Malaysians. Only then it is fair.
