Sameer you seem to be a little out of touch in regards to religious significance of ramar setu or its mention in books(evidently you have never read valmiki ramayana)...Rameshwaram the place where the bridge begis has long been a holy place and floating stones of rameshwarm are a well known wonder, also please remember this bridge is pre-historic and now under the ocean(atleast not visible to naked eye) just like the submerged part of dwarka(i bet you will not see people swimming under water to pray). Its not becoming an issue because of BJP, this is an issue for BJP(one party in India that atleast adresses hindu rights)..if it is a ploy then all hindus are ready to be a part of it
